With a boiling point of 36 degrees celsius, this solvent might be a bit heavier than butane but still functions well for cannabis applications. Eventually, the HTSFE will have small amounts of terpenes present with large crystals, or many small crystals, and it will be ready for the final purge. I have a half pound of green wax, Maui Waui, it's orange when looked at in the light. The water will drop through the iso layer and into the bottom layer at first, oulling polar compounds with it. Dark green or dark amber? So, can I evaporate hexane out, after polishing, for reuse purposes? The most dangerous thing was not consuming cannabis, it was getting caught with it.. Then the idea behind DCVC is that a continuos solvent gradient is fed through the system starting with an extremely polar solvent. There are orders of magnittude less solvents used in this process compared with Flash Chromatography. Extremely potent this way, likely owing to the possibility of DEEP lung inhalations without coughing. I tried this with some older trim that was run with butane. Studies of shoe repair folks suggest that long term chronic exposure at lower limits can have long term effects, because the liver converts n-hexane to Hexane 2.5 dione. You can get 95% grain alcohol shipped to your door at www.culinarysolvent.com. Can I put it in a jar of Eveclear in the sun for 2-3 hours, then rubberband 2-3 coffee filters on the jar and filter out the green Everclear? C2H6O(Ethanol) wil atract and retain H2O. Anthony DeMeo is Co-Chair of the Extraction & Manufacturing Department at Oaksterdam University. There is a SURE fire way to remove the polar substances from your extract, and furthermore purify your compound to either a pure cannabinoid product or nearly pure. #11 if small unwanted seeds start to appear over time isolate wanted seeds repeat step #7 and up I saw that middle layer getting thinner and thinner and harder to see each time, as I felt like I got more out of it. My results came by googling "salting down alcohol". . 70% iso and 30% water is what the label says. and a vacuum assisted buchner funnel. The picture was my ex-spouse. Then I add the ISO/hexane solution + 100 ml water to a separatory funnel, I shake and let settle. It would eventually air dry in a thin film, but vacuum is so much faster, and more reliable. The Hydrogen Peroxide treated extract boiled dry of HP is as smooth as silk smoking in a pipe (over fiberglass) but sucks the big weinie in a vaporizor. nope. Anyone I can email with or speak to? #12 once pentane gets to the point where your crystals are not covered or your impurities are getting too concentrated ,remove the wanted seeds then fast crash the pentane solution by keeping the lid off repeat steps #4+ once solution has evaporated the pentane leaving unwanteds+ THC-A, Thanks @Terpjesus. So I take advantage of a lot of acetone/extract mixes by experimenting with it after I cleaned up my glassware. I have. Put back into freezer for a couple of hours and repeat 2 more times so you have a good clean product. Also wanted to polish BHO with Everclear. THCA is white when pure (or close to pure). The Pam was used to lubricate the blades on an automatic trimmer and contaminated the trim used for this particular extraction. It begins boiling off the iso/water immediately. While it is easier to use a process that minimizes their extraction in the first place, if that is a moot point, because you already have an extraction with excessive non-active ingredients, here are some ways to clean them up: After re-dissolving the extract in ethanol or hexane, it may simply be filtered to remove the material that is insoluble. I tried many times to repeat the process but couldn't get the same thing to happen again. If you intend to produce a THCA crystalline with above 99 percent purity, you will need to perform these washings. I have gone to using activated carbon pellets only in the vapor stream of my Vapir One vaporizer which is packed with carbon pellets in the chamber that the vapor passes into prior to the breathing tube. Would have a question for you. I've been fighting with this process and I'm trying to figure out exactly what I'm doing wrong or still need to do. Light smoking will occur if particulate is present - the goop oil will stop smoking though. Yeah once they get that big it becomes difficult to get enough thca to continue to grow them even bigger. https://future4200.com/search?q=CBD+pentane Even at the hobby level for me it gets spendy to just evap it all. And filtering through AC and DE? I have used salt in my trials but only to get pure isopropyl from rubbing alcohol. From your post I assume you are also after THC. - Despite the dark color of the end product, what do you reckon is the actual THC concentration? into the stainless steel container the mash is in whilst still hot after coming out of decarbing in the 250 oil bath. Cite. Its much easier to begin nucleation with an oil that has most undesirables removed (e.g., fats and waxes), so winterize the oil before you begin. Thanks. Shake well, stick it in the freezer fro two days. As you may know, anything above 15 is considered polar, with water at about 80. I have much experience clarifying extracts in a number of ways. This is our main concern. At room temp it is constantly decarbing judging by the experiments with time lapse photos up close to see it. *A strainer works well for seperating the rather pure thc-a from the chunks Are people also idiots who do that too? Turn on stirring and turn on the heating bath and set to 45 C. Soooo, what if the extraction is really, really messed up, or if you just want to see how purdy you can make an extract? In a ball jar, with a lid put in your Onion, then add 3x the amount of Ethanol. #7 once you are able to obtain yout purified thca granules (90%+/-) re dissolve into new pentane hotplate in safe area with minimum heat <90f .try to use as little as possible as needed or it will take longer example (77 grams in 300 ml pentane) The process is known generally as Dry Column Vacuum Chromatograph (DCVC) although the only references I find online relate to the method as used with silica gel as the stationary phase. I will post pics of my crystals when they are bigger. Pharmer Joe has successfully removed them using column chromatography, and with a Kugelrohr, Pharmgold Terp Trommel molecular still, as well as filtering through mixes of rare earths and clays. May Life not life on you too often. I scraped it up and vaped it and honestly couldn't tell the difference at all. I am sure about others, but for me Hexane is very expensive. In column chromatography, which takes HOURS for even small samples and simply cannot handle larger samples, a solvent gradient works by passing a solvent through the column that has very little or no ability to disolve the sample and carry it through the stationary phase. We used 20 grams of oil and around 200ml of Pentane & Hexane mix. I'm always looking for you folks to clean up my ongoing (and seemingly neverending) RSO apprenticeship :-) Repeat and wash the crystals as many times as needed. Any suggestions? They list n-Hexane as a class two solvent with 290 ppm concentration limits, and a total PDE of 290 mg/day. Could I use pure acetone to re-dissolve my oil (as I use acetone to extract it from plant material anyways) and then simply salt water-wash that in a separatory funnel to clean it, then evaporate the acetone on a 140F hot plate? I use aluminum oxide as the stationary phase and the solvent system I use is water/iso mix. The described process is called diamond mining in the recreational market. Hopefully, improving processing techniques and purifying cannabinoids will help lead to future cannabinoid-based research so we can begin manufacturing cannabinoid-based drugs for treating specific ailments, thereby moving away from the anecdotes that we have today. Have you personally smoked or vaped extract with dust in it? Vaping the "splat" is an experience in hacking and choking. Good luck. #10 add big seeds( at this time your saturation and purity levels should be ideal.) I use isopropyl alcohol and water as a solvent system because it is inexpensive and much safer from a fire hazard and fume point of view than systems that use hexane. Hence floats on water. Was thinking this may be a good experiment but I think the main impurity is oily so would probably migrate to the hexane layer. The report states that at oral doses of 5 - 10 ml (extract is almost precisely 1 gram per ml) that some children begin to display nausea and other icky feelings. Its also a thick honey texture, which is kind of a pain to work with. So I am working on extracting some lovely compounds from plant matter only problem is I left it in alcohol for several days longer than expected. keep in mind evaporate too fast at this time and you will get unwanted contaminants trapped in the crystal lattice you want to evaporate reaaal slowy but not just sitting there or it will pause the process ( crack a ball jar lid as little as possible) I'm wondering if it will be possible to remove pam cooking spray from a run of bho. ISO wash done at room temperature, overnight. - Do we really need salt in the water? Lab coat. - How much should we reduce the volume of the methanol? I added a bit of steam distilled terpenes to the top of the solution, to ensure stratification. Loved the question part at the bavk also, very educational. I strive to recover the $100 per gallon hexane and other spendy solvents but when they are mixed it is just too tough for me to get a clean seperation so usually they get evaporated. Do you honestly believe the extracts you obtain do not have dust, eyelashes, bug parts, and every other thing that floats around in our atmosphere? https://www.google.com/search?q=onioin+extract&ie=utf-8&oe=utf-8#q=onion+extract&tbm=shop. The bottom drip is scraped off and vaped - nearly zero irritation and yum yum yummy. Rock on Oregon. QUICK READ: How can one obtain a shatter consistency with an ethanol wash/winterize, if not what is the best way to evaporate Ethanol? PS: On the valid subject of dust control, a cheese cloth covering will aid in dust control, as will operating in low dust conditions. We feel the purity of our medicine would be irrelevant considering there are no alternatives due to tyranical laws. What is not known is how effectively the separation of the extract components are when the extract is disolved in rubbing alcohol prior to salting it. Did you actually read the article, or just look at the purdy pictures? feel free to add any advice fam. What temp to let sit out at? Cthis will preserve your terpene profile. Simple filtration, even at that micron level, takes stuff out of suspension, but not out of solution. At 250F, there won't be alcohol or water left. Bottom line, all this hexane method. Thank you sir or miss! Clarified neem oil is said to be hydrophobic. Inhalation. It has a burnt taste not normally present when vaped above 365F but is sweet below that. The best method is to create butane hash oil (BHO), and then purge it at about 90 degrees Fahrenheit. Unless of course you vaped first and an alien worm with horrible fangs jumped out of your gut immediately after you started hacking violently. In that patent they mention the same kind of azeotropic behavior shown here when using hexane and water as well as the primary patent application that soecified isopropyl alcohol at 91%. Should I use non ionized salt? Thanks! 1) It is IMPERATIVE that all traces of hexane or any other solvent be removed. Once you redissolve and have it at the saturation level thats desired, do you just pour that into the jar with the large seed? The issues I am having is that I do not get a distinct phase separation between the water, emulsion and hexane layers. After the fats and waxes have separated, I use a Whatman #1 Lab filter, accompanied with an unbleached coffee filter. Sweet amber dreams. I cannot know if this would work for you because every parameter often gets adjusted "on the fly" as I do my own. If I can ever help in any way, let me know. Washed 5 more times with just saline water. We give away free process information. My procedure is as follows: The only thing I have extracted by intense boiling in water is some pinene which is partially miscible in water (no idea about salt water here). If you even leave a small amount uncovered in a closed room for a night it will collect dust. I use HPLC greate 99% hexane. Most users consume diamonds in a dab rig by heating the dab nail with a butane torch and applying a "dab" of diamonds inside the heated nail to vaporize it. This method is as safe as any method and I personally consume 100% of all extracts I process. I can even take the extract so cleaned up and when placed on a cool glass surface can seperate the components easily with a flame above the goop and a tilt to the surface. I only have one video which only shows one step and how effective the process works just as a pure filtration method rather than seperation. The flow keeps the filter membrane swept clean as it passes through, so the flow concentrates and the clean stuff weeps through to the outside. Vapor respirator. About 5-10 minutes later the bubbling settles down so it looks like fizzy cola a bit with uniform and slower bubbles. When you prepared this, was the Onion "Dried"? How long should i wait before the ethanol is gone, always seems to have a slight smell to it. Joe came up with this process, which has produced our most pristine creations. Safety glasses. Get some integrity already I wish I could post pictures, but what it looks like, is a perfectly clear big thick layer on bottom (of salt water) and a gunky, kinda fatty layer in the middle (I'm assuming this is the emulsion layer though I'm not entirely sure what that means because it wasn't explained) and then the dark hexane mixture up top. When I class chlorophyll with the water solubles, it is not in the same vein as the term is used in inorganic chemistry and is more involved. We use premium flowers - the quality is certainly there, still, we are hung upon being able to advise accurate dosage. I have never had any evidence that an acetone/extract mix can be "washed" with water. At this point, I have concentrated it down to a very potent, yet very dark matter. Each time you pour off the terpene layer and leave the crystals behind, the potency increases. . The first clue of course, is that it doesn't come in nearly as attractive a container, and the second is the MSDS information which tells us, that in excess, N-Hexane attacks our nervous system. The flame gets intense. What would happen if you put an oil extract through a reverse osmosis system? It is interesting to note that rubbing alcohol, being a mix of pure water and iso, cannot be fractionalized through evaporation. A couple of points, and as the first seems to be based on an ASSumption on your part, I will give you the benefit of the doubt and infer it is from ignorance, as opposed to malice. or not? I'm also allergic to chlorophyll so I'm trying to kill two birds with one stone and stick to alcohols which I react much better to. Hexane grabs all of the medicine for sure, but the real point of this article is to show one posssible use of it. or just that less time is needed? Once that's done, seal the concentrate in a container and leave it for two to three weeks. To wash with ethanol, redissolve the hexane honey oil in ethanol at a ration of about 10 to one and boil off the alcohol. Note also that oxygen in a breathing atmosphere greater than 75% pure will kill us dead! I doubled the hexane from 100ml to 200ml total and voila! After it has separated, bleed off the water and emulsion layer. Nice and cheap is great! Because brother, I have found when refining dispensary extracts; fitting grease, eye lashes, tiny flies, unidentified dust bits and have added on accident some of ose those things myself. I use a rod in the lip end to plug the cigarette and to hold it comforatbly from the heat. Repeated washes from then on got a huge amount of the green out and fats and so forth. I notice lint in it. We used around 8 liters of water and 3 liters of methanol. https://pubchem.ncbi.nlm.nih.gov/compound/5281303#section=Top. I got your book. There are solvent polarity charts online. My plan is to just keep doing this to see if they continue to grow. It has extremely low volitility. at a certain point the polarity will become just right for the cannabinoids to pass through the column. Routes of Entry: Absorbed through skin. I believe from multiple experiments that I have conducted with $1000's of my own money and my own legally obtained extract here in Oregon, that this is the quickest, safest, and cheapest way to clean the extract for ultra purity. 100% no moisture. After filtering, the alcohol is evaporated or vacuumed off, to leave a pristine Absolute. GW. Heck, I even get little gnats that land in it. Without testing you cannot know these answers. They differ a lot in price though. Have seen a clear terp online and am wondering If any one has info on how to achieve it. The THCA content of these crystals can be as high as 99 percent but can fluctuate depending on residual solvent and terpene content. Should you add the everclear to the butane/oil before it has evaporated? Experience has proven to me that this is the moment to stop heating it and put turn it up for the drip to form. While THCA is a useful cannabinoid on its own, the synergistic effects of cannabinoids and terpenes are not to be underestimated. Smell testing is important. Make sure your work area is dust/contaminate free. I wish to retain the antibacterial properties of the extract as well as wish to obtain a powdery product. Dale talks about fighting to free cannabis prisoners, staying active in cannabis advocacy, and reducing the stigma around the plant. I am positively certain that the product is fully decarboxylated and my oh my is it potent. FDA lists Hexane and Methanol as Class II solvents, while Ethanol and Pentane are Class III. This is my sop (without getting into minute details) it really only is efficient for 100+ grams of thc-a otherwise there is a significant loss The waxes left over, by the way, work GREAT as a skin softener. 2023 Wise Education Technology Inc. All rights reserved. Just asking as I have not much access to hexane or usable light naphtha, all I have access to are generally acetone, isopropyl alcohol, ethanol alcohol, and water/salt water. Once the desired diamond size is achieved, pour off the remaining layer thats comprised primarily of terpenes. D. Gold. I'm looking for an older link you posted to terps you bought off line. I vape it anyway lolz. Last month I dropped a hot beaker I was refining on my hardwood floor. You seem to be blissfully unaware that we don't sell any concentrates to anyone, period. Thanks for your time, Reverse Osmosis is sort of like pumping a solution through a blotter paper straw. I then pipetted room temp HPLC pentane on top of it, swirling it around until dissolved. Remove when brisk bubbling is over. There wasn't really enough that precipitated out to smear onto paper to see. From the sounds of it, you say you can't get it to dry out. C over the course of 5-30 days. It works without question and the only product loss will be the polar compounds which will not pass the alumina column. While THCA is a useful cannabinoid on its own, the synergistic effects of cannabinoids and terpenes are not to be underestimated. Boy Howdy!!!! When enzymatic cleaning chemistries are used in washer/disinfectors, they typically work best between 100-140 F/32-60 C with detergents typically being used in ranges between 122-180 F/50-82 C. This can vary . Preliminary research into THCA has shown this cannabinoid possesses anti-inflammatory, neuroprotective, anti-emetic, and anti-proliferative properties. D Gold, Author of Cannabis Alchemy, 1971, Shares Cannabis Extraction History Unfolding! Thanks for the reply, but when I mentioned 'denatured alcohol' I meant ethanol, not IPA, incidentally, I got 99.9% IPA off ebay, nice and easy, nice and cheap. So just to check in case I'm being a bit thick IPA can be used to purge hexane from an extract instead of the ethanol mentioned in the above article, bearing in mind the less-than 0.1% water content of my IPA? Since you are posting on a marijuanna site I assumed of course your concern was neem oil as an insecticide which contains the naturally occuring azadirachtin. DISCLAIMER; I do not condone using this method where as any extracting methods are consider dangerous. I siphon off the amber precipitate with a medicine dropper. In my attempts to polish with hexane I have done the following: If you have a dewaxing column, you can utilize this to assist in further removing undesirables. Another nap. We did a quick wash and it still came out dark. Shatter consistency is caused imo by impurities in the extract. Then, pulverize/blend into a fine consistently. When you smear it on white paper, is it green or brown? Instead, we'll wash our current solution with hexane and water, removing chlorophyll and whatever else goes out with it. Step Five: repeats several times. keep pentane in liquid state if becomes oil like viscosity add a small amount of pentane too much and you will dissolve thc-a too little and you will not be dissolving the unwanteds anymore While we use HPLC grade hexane, light naphtha containing only Pentane & Hexane will also work for this process. Besides simply smoking THCA crystals and/or mixing with flower, formulation specialists may want to combine these diamonds with terpenes or other cannabinoids to create a unique treatment for medical cannabis patients. Could I potentially do this to a fresh extract as well to wash for chlorophyll so I don't have to work with hexane at all? (/d-gold-author-of-cannabis-alchemy-1971-shares-cannabis-extraction-history-unfolding/) Comments. Can the solution just be left to air dry for several day's?, or do I need to Hexane is as easily recovered as Ethanol, using the same techniques. We were right all along. That long process results in 99.96% THC. Thank you so much! Creating unique mixes from THCA is precise chemistry that will spawn thousands of future products. btw 98% is completely false. In the video I am processing extract into a more refined product which I vape happily, and the video starts as the centrifuge of the isopropyl alcohol and extract mix are finish slinning the waxes out. Hopefully, improving processing techniques and purifying cannabinoids will help lead to future cannabinoid-based research so we can begin manufacturing cannabinoid-based drugs for treating specific ailments, thereby moving away from the anecdotes that we have today. I have not included the full details as I have been asked not to discuss this in this site for safety reasons. In Flash Chromatography you NEVER let the column go dry or it fails the column. Do you have an email graywolf? Part two. I have successfully purged to nearly pure so many grams of extract that my cupboards are overflowing with tiny plastic pucks and their lids lolz - AND I cleaned them out already!!! Step Two: I load my raw extract into a ceramic cigarette. What would your recommendation for maximizing the yield be, without doing a warm extraction? We still send out samples for others material to test for pesticide, but if you know the history of material that you've grown yourself, you should know what you used. Plus, putting your jewelry away safely while you bake, apply cosmetics, or garden helps keep debris from building up in and around the setting. Even the saturation of the water with salt cannot be predicted very well. It helps purge the residual butane. Rubbing alcohol is the label. We would be happy enough If we found a way to test the potency of our extract. We buy the salt cheap by the bag, using salt intended for water softener use. The real question, putting aside your personal attack, is this; "What data do you have that suggests the dust or debris that might collect in your extract is harmful to human health vs. an advantage to human health? Do you do this with your cold crash crystals ? Cook at 275 F for one long nap, or until any visible signs of smoke or vapor cease. When you are cleaning up really gunky stuff it might be more practical to use 10% increments. Hm! Doing so will evaporate most of the butane. Acetone is hands down the solvent of choice for cleaning extract and the residue it leaves in a boiling flask. No chemicals involved ! Ended up a little dark so I ordered a gallon of hexane, warmed some up, and dissolved oil in it. Synonym :n-PENTANE; Normal-Pentane; AMYL HYDRIDE; 2-methylbutane; isopentane; Normal pentane; NSC 72415; n-pentana SDS # :001133 Airgas USA, LLC and its affiliates 259 North Radnor-Chester Road Suite 100 Radnor, PA 19087-5283 1-610-687-5253 For iso, it takes (I am told) 15 grams of iso to really cause hurt most sane persons wouldn't want. This low and slow method will encourage more nucleation due to increased temperature and pressure and larger crystal growth. My extract begins to decarb noticably with very little heat. Tattered old wolf, So put in a large seed. It is a sort of thin film chromatography separation and works surprisingly well for seperating the components of an extract. So from now on, I will only do "mixing" outside of my main mash tin - that way I can still reclaim the little bits of precious. if not add small amount of pentane ( a few mls) untill you see a close to white color in the thca layer dont add too much ! The goop will run down the cool glass and become solid as each component in the goop cools to the point of this phase transition from liquid to solid (more or less). One article cannot cover the multitude of variability encountered in our pursuit. Please enter your email address. The hexane/oil remained dark, but though we must have done it right already We purged - the oil was still black. Step IV: Wash the oil in a pentane solution to remove any remaining plant matter residue. I do not extract but from time to time get flower to puff. Solvents in Class 2 (Table 2) should be limited in pharmaceutical products because of their inherent toxicity. The rest feels toxic when inhaled. They contain both the undesirables, and the alcohol as well, with the cannabinoids left with the hexane. I that case, I would switch to ethyl acetate and try again oops, here is the site it's some sugary cumbly wax. One thing I notice is it takes quite a long time for bubbling to become visible. Bigger chunks bake at 275F instead of 300F to avoid burning. I pick the pieces off with frozen tweezers. We must have repeated this at least 10 times. http://www.coleman.com/uploadedFiles/Content/Customer_Support/Safety/lantern.pdf Hexane has been unpredictable for me in the seperatory funnel in terms of repeatable results. Whether the diamonds are smoked or added to flower, some people are gravitating to purer products across categories, and 99 percent THCA is grabbing attention. Saw @Future4200 did a pentane reX on his ig a while back was trying to find some more guidelines before I try it. Run the rotovap again. I think it was moonshine derived but not finished. Isopropyl alcohol always has water in it so that was involved. We start out by making four or five liters of saturated salt water in a glass (or ceramic) container, by mixing sodium chloride (table salt) in hot tap water with a hand mixer until no more will dissolve. It will remove nearly all the odor and "terpene" rush you get too, but the medicine that I am after is THC and that is joyfully intact and as decarboxylated as it can get without further time and heat. Given the extremely low toxicity of the product to humans I personally would not hesitate to vape the oil after I did the above procedure.
