I'm looking for an older link you posted to terps you bought off line. Hope it helps. Shake well and then lift the lid long enough to burp any pressure, before setting it in a stand to stratify into layers. You can see a color gradient between the water and the hexane layer but it is impossible to tell where one starts and one ends. The mind change is unmistakable. I had some weedahol (Green Dragon) that was clearly not decarbed before hand. I am curious, could this method work using acetone instead of hexanes? Acute toxicity of the gas (LC50): 48000 ppm 4 hours [Rat]. I use aluminum oxide as the stationary phase and the solvent system I use is water/iso mix. WARNING: THE LC50 VALUES HEREUNDER ARE ESTIMATED ON THE BASIS OF A 4-HOUR EXPOSURE. It doesn't have to be a lot. Since purity is already so high and it is in crystalline form this should be relatively easy given the correct procedure. With iso it actually breaks the azeotrope between water and alcohol, forcing those two into seperate layers by themselves. Coleman's MSDS identifies it as light naphtha with a boiling point above 100F, so check out a typical light naphtha MSDS also attached. https://skunkpharmresearch.com/evaporator-chamber/. The diamonds I had took maybe 10 mins to dissolve but its a noticeable difference. . I am having a great deal of difficulty acquiring non-denatured alcohol for the scrubbing of the hexane, what other solvents can be used to get rid of the last of the hexane, or is using denatured alcohol (denatured with MEK boiling point 79.6 C) ok? I think I am on the right track, but just wanted to get some feedback from the community. May Life not life on you too often. Have already washed diamonds and worked out well. In a ball jar, with a lid put in your Onion, then add 3x the amount of Ethanol. Place in freezer. We buy the salt cheap by the bag, using salt intended for water softener use. I decided to cook it into a decarbed QWET oil (I follow your HOA recipe, sublingual) after straining, freezing, and straining again, but when it came time for the final 1/8" of mash that was left, it just wouldn't (visibly) go to decarb at 250F (I noticed a rainbow sheen to the bubbles), so I stopped and decided to try and air dry the remaining ethanol off. Any solvent placed into an oven, as in step 2 will ignite as soon as the vapor reaches its flash point. 4) I would pass this mix into 20 ml centrifuge tubes through a lab filter. GW. If you intend to produce a THCA crystalline with above 99 percent purity, you will need to perform these washings. This terpene layer can be poured into a secondary crystallization vessel with the steps repeated to allow for further precipitation of THCA. When performing your extraction, its important to chill your jacketed extraction system to -50oC or colder. American Pot Story: Oaksterdam highlights the journey of cannabis advocates and concerned citizens in California during a time of significant change. what if it is green? How are you getting it to be 1 big rock like that, start with one big seed then re dissolve extra crashed thc-a periodically. See: http://www.nlm.nih.gov/medlineplus/ency/article/002893.htm for details. http://www.collectioncare.org/MSDS/naphthamsds.pdf . Washed 5 more times with just saline water. Step Five: repeats several times. Diamonds may be tough, but avoiding knocking them against hard surfaces (or dropping them) can go a long way toward keeping your gems sparkling. This is off the question topic, but I will comment I do use acetone to clean up all my glass (I burn extract/solvent inside ceramic dishes so it gets gunky). The third time it was even lighter, but the hexane/oil was still dark. Diamond Hazard Value Description; 4 1 0 Health 1: Can cause significant irritation. Inhalation. About 2-3 inches. I'm wondering if it will be possible to remove pam cooking spray from a run of bho. FDA lists Hexane and Methanol as Class II solvents, while Ethanol and Pentane are Class III. Excellent post, we'll definately look into this in the future, sounds quite interesting. Deadly poison if you drink it. Thank you again and best wishes! Once you redissolve and have it at the saturation level thats desired, do you just pour that into the jar with the large seed? Pleasant tasting frankly. 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? Get some integrity already This presumes that your goal is to remove the chlorophyl only. Your time is always much appreciated, Skunk Pharm. thank's for the information. We still have just one question - does the Hexane/Saline water wash impact the yield? Extract doesnt like salt. The THCA content of these crystals can be as high as 99 percent but can fluctuate depending on residual solvent and terpene content. Rubbing alcohol cannot be separated by distillation - the water and alcohol won't separate that way. #6 filtering: pour slurry into buchner funnel after filter is ready and set. I tried this with some older trim that was run with butane. The smoke is horrible so I don't believe any THC is left at this point. Once, a mix of hexane and acetone and water in my experiment formed a layer underneath the hexane. nope. 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? It seems like the colder I got the salt water, the more of that gunk I was able to pull out each time. I see stuff on Google in this thread but I can't find it. Pentane recrystallization - Extraction - Future4200 I saturated the oil in ethanol, ran it through a vacuum assisted filter using a watman 1 filter, pulled out a ton of gunk, then dumped hexane and saturated salt water into the seperatory funnel as instructed, poured out the water and ethanol mixture, using the funnel, saving the hexane and terpine mixture that was the dark color on top, just like the picutres, and I have been running salt water though allllll day and the color isn't getting any lighter. In minutes it hardens into tiny air pocket ridden pieces. I've looked into carbon filtration a lot, but this is the first time someone gave an actual number as to what is lost. Close the vessel and very slowly increase the temperature to 25-35oC over the course of 5-30 days. dissolve it in rubbing alcohol completely. Be sure to use an approved/certified respirator or equivalent. First of all any salt will greatly impact the miscibility of alcohol and water. 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. I notice the first pull down to -29.5Hg lets the extraction boil off very rapidly, then slows to a crawl. Pentane is a highly non-polar, light hydrocarbon solvent, that acutely dissolves THC instead of plant matter. As a matter of fact, prior to winterizing I intentionally add dust or sand of some sort to the disolved mix which increases wax removal orders of magnitude better that filtered extract/solvent. Drained again. These techniques are for you to further explore and expand your understanding of forming THCA diamonds. I added several drops of pentane in order to get the remaining BHO crumbs to dissolve. I captured it and it was acetone (smell). My favorite is to gravity drain your sauce in a colander and leave them a little dirty, because, you know, terps I call them dirty diamonds because they're unwashed. While n-Hexane is a delightfully non polar solvent, that enables us to do some amazing things, it has two more carbons and four more hydrogen atoms in the chain than Butane, and so due to the greater Van der Waal forces involved, is not as easy to get rid of as Butane. I use a medicine dropper to remove the amber layer. The alcohol will disolve into the hydrophobic components of the extract and neem oil present and give the water (which forms an azeotrope with the alcohol) a way to be presented to the hydrobolic component like azadirachtin and alpha pinene. The issues I am having is that I do not get a distinct phase separation between the water, emulsion and hexane layers. The water layer underneath was clear. In my experience, the level of pressure and temperature dictates the type and size of crystals you achieve. Dissolve the entire batch in just enough rubbing alcohol to make it dissolve. Thanks After this time, remove the vessel from the cold environment, open the vent valve, and allow the solution to reach room temperature. We think reducing it 10 to 1 or 2 should be safe. Below 10 degrees celsius, outdoors, not frozen 90 seconds wash. do a vac purge? 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. washing diamonds with pentane Im attempting to do a THC-A crystallization with pentane and would like some feedback/criticism if possible from those whove successfully used pentane as a crystallization solvent. I will post pics of my crystals when they are bigger. We use an HPLC Reagent grade for this purpose, which we get from the local scientific supply store. Oops! Pentane is about .004% water soluble and Hexane is about .001%, so not a lot goes out with the water wash. https://erowid.org/archive/rhodium/pdf/solvent.miscibility.pdf You seem to be blissfully unaware that we don't sell any concentrates to anyone, period. We were able to justify the cost based on the number of samples we ran and the cost to have a lab run them for us. Link to a pdf of the issue here. Rock on Oregon. I have tried this saline/hexane wash before on some oil few years ago. When you add salt to the mix it is very tough to know how that impacts things. This method is as safe as any method and I personally consume 100% of all extracts I process. I wring the tea bags and am left with white waxy stuff and other solids. This article was written by Michael Sassano and Anthony DeMeo of Somai Pharmaceuticals. Flash point 57F. without seeing the stuff. And then repeat steps 1-7? It occurs to me that marijuanna is often grown outdoors as well. Even used as a purely filtration method using 70/30 iso to water ratio the filter will catch most of what you do not want as medicine. Rubbing alcohol is the label. Pour off mix into seperatory funnel. 5) Spin the tubes at 4000 rpm for 20-30 minutes. 3. level 2. Diamonds have unique colorations and clarity that are derived from terpenes and the purity of the crystalline structure. 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. I would suggest chilling both the material and the alcohol to below -18C/0F and doing multiple quick washes, keeping them separate, or switching to a non polar solvent at the same temperatures. What would your recommendation for maximizing the yield be, without doing a warm extraction? I am not suggesting this process for reclaiming ashtrays, but simply to make a point. Let it sit back into the freezer for another 2-3 hours so sediments will settle and plant waxes, lipids and chlorophyll will coagulate. Dale talks about fighting to free cannabis prisoners, staying active in cannabis advocacy, and reducing the stigma around the plant. The waxes will precipitate out of solution as the temperature drops and clump together so that they are easily filtered out with a standard coffee filter, or a Whatman #1 lab filter. Once the vessel is filled, tightly close and chill it to -75oC or colder for 48 hours. I modified the screen a bit to accomodate extract. Chlorophyll itself has a polar head and hydrophobic tail, so it is mostly non soluble in polar water, but can be removed from the plant and conveyed by water as micelle. It is a sort of thin film chromatography separation and works surprisingly well for seperating the components of an extract. Even then, pulling the product through will take horsepower because there will be so much unwanted material it will tend to plug up. Also wanted to polish BHO with Everclear. C2H6O(Ethanol) wil atract and retain H2O. I do not extract but from time to time get flower to puff. The picture was my ex-spouse. What am I doing wrong, can someone please help! Next month I plan to do a vid from start to finish and present the results in a video to show it. washing diamonds with pentane. Already among organometallic compounds there are examples in which obtaining crystals at all is an enormous struggle and having single crystal quality is simply a matter of hope. On another note, we are not that sure anymore about complicating the situation further with additional processes. The oil becomes hard and taking the dish out, the water left melts first abd pours off easily. In my humble opinion, you are doing it absolutely right. We've observed that when evaporating 1 liter of methanol, hash oil starts forming in the last 50ml. 95% thca cristals are white. If you have a dewaxing column, you can utilize this to assist in further removing undesirables. I get acetone from Amazon labelled as "Pure Acetone Nail Polish Remover" by the quart. ( depending on your material and type of alcohol you use). It appears however that azadirachtin by itself is hydrobolic and miscible in water. When you say acetone/water experience, is this including salt water? Water also dissolves and washes away the Chlorophyll binding proteins and exposes the Chlorophyll to the solvent used. You can also place out in the sunlight for a few hours to breakdown more chlorophyll before placing into the freezer for the last time. It has been two days, and I have the usual black blobs that I can redissolve again (I have a good 5 grams of actual oil by eye estimation), but there appears to be about 2 tbps of red cough syrup that smells strongly of raspberry that doesn't appear to be willing to simply evaporate. I cannot know if this would work for you because every parameter often gets adjusted "on the fly" as I do my own. Isolating cannabinoids to their purest form, such as THCA diamonds, and recombining them with terpenes is the first step in creating treatments that target specific symptoms. I use HPLC greate 99% hexane. #4 feed hc into jar slow agitation swoosh liquid around in jar you will see it start to pull the unwanted parts of the thc-a out. In Flash Chromatography you NEVER let the column go dry or it fails the column. GW explained that activated carbon can clean up extract and he is right, however i have used it extensively in tests and irregardless of how I extract with it the activated carbon will indeed absorb cannabinoids along with the other material. Hexanes dielectric index is closer to 1.3 and for all practical purposes, isn't miscible, so I thinking not. Remove when brisk bubbling is over. Once youve achieved your desired crystal growth, purge the residual solvents from the terpene layer and crystals using a large glass (e.g., Pyrex) dish that allows you to create a thin layer of terpenes, maximizing the surface area. You can continue to grow larger diamonds utilizing super-saturated hexane and to improve the clarity of your diamonds using chilled pentane washes. I recommend against using Coleman camp fuel, because of what is in it, and how much harder it is to purge than just Pentane or even Hexane. Boiling point (at 760 mm Hg): 68.9 degrees C (156 degrees F) 3. https://vimeo.com/172564716, I really like what you guys are doing. I do not believe that the presence of salt impacts the relationship that water and acetone have. Thanks for your time, Reverse Osmosis is sort of like pumping a solution through a blotter paper straw. I do not recall any experiments with salt water and acetone. Ever try winterizing at -80C (or anything lower than 0?). Washing dirty diamonds - Crystallization - Future4200 Then, reduce the pressure in your system to -30 mmHg, or as low as you can go based on elevation, using your vacuum pump. We would be happy enough If we found a way to test the potency of our extract. THCA is white when pure (or close to pure).
