thank's for the information. Same concept applies to pentane vs heptane. Reactivity Alerts Highly Flammable Air & Water Reactions Highly flammable. Perform your extraction as normal but maintain a ratio of solvent to biomass between 6:1 and 10:1. It would eventually air dry in a thin film, but vacuum is so much faster, and more reliable. While THCA is a useful cannabinoid on its own, the synergistic effects of cannabinoids and terpenes are not to be underestimated. Each time you pour off the terpene layer and leave the crystals behind, the potency increases. Here is a link to a DIY evaporator that addresses that issue. This step isn't essential, but it did seem to help. 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!!! They differ a lot in price though. This time we decided to wash with methanol and saline water every second time. Secondly, this polishing article on ashtray reclaim was simply to make a point, not suggest a source of dabbing concentrates. All Answers (6) treated generally refers to washing the reaction mixture.Do no throw the ether.It is generally wash ether that you can use it again.MgSO4 is a dehydrating agent.So you just place . In honor of 4/20, Oaksterdam University Executive Chancellor Dale Sky Jones speaks with Karina Nova at ABC7 News in the Bay Area. After the fats and waxes have separated, I use a Whatman #1 Lab filter, accompanied with an unbleached coffee filter. Pleasant tasting frankly. #5 if top liquid pentane layer is too dark and crystals on the bottom are not close to pure white let the thca settle, slowly pour off/siphon off top layer, try to stop if you see some thc-a grains coming with it.Now If liquid layer is light in color with a water like viscosity proceed to buchner funnel filtration. Simple filtration, even at that micron level, takes stuff out of suspension, but not out of solution. The separation is obvious to a sighted person. Very interesting. Pour off mix into seperatory funnel. GW. I am thinking of peppers. I use aluminum oxide as the stationary phase and the solvent system I use is water/iso mix. Since you are already involving Hexane in the formula, why not extract with it in the first place? Please suggest. Also I have bled off some of the bottom layer and replaced with fresh water, even after 10 additions of fresh water I notice no color change in the system it is still dark and nasty. Drained again. Any feedback would be hugely appreciated as I have about 3 and a half liters of extremely concentrated oil dissolved in ethanol that I'd like to keep running. The magic trick is two fold. We are outside the States. Salting down is a method of fractionalization for this solution. Two Dawgs ISO wash done at room temperature, overnight. At the time I did not think anything of the yellow layer but save everything to study later. dissolve it in rubbing alcohol completely. Cook at 275 F for one long nap, or until any visible signs of smoke or vapor cease. I have my freezer set to max and my thermometer show a temp just under -10 C. The water components freeze and the freezer dries it. That hasn't been my experience where over saturation had helped to precipitate out of the fats, definitely hard to find that balance and I'm not sure the advantage would be worth it, It only matters if your going to put into your crack pipe.. Any ideas? If they are growing slowly this is the ideal saturation level. QUICK READ: How can one obtain a shatter consistency with an ethanol wash/winterize, if not what is the best way to evaporate Ethanol? 2) THC does not significantly break down with the application of extreme heat so long as oxygen to oxidize the THC is present. Without testing you cannot know these answers. Hey Skunkpharm, this post, while interesting, is contradictory and confusing: first you say: "After it has separated, bleed off the water and emulsion layer), and then: "After carefully bleeding off the bottom layer of water, we continue to replace it and repeat the wash process of both the emulsion layer and the hexane solution, until the emulsion layer disappears" Which is it, and why? Skin: SOAP WASH PROMPTLY - If this chemical contacts the skin, promptly wash the . Hello!! Then I add the ISO/hexane solution + 100 ml water to a separatory funnel, I shake and let settle. The deviation from routine extraction begins here. So time, temp, state of decarboxylation(therefor boiling point and acidity), residual solvents from extraction, and a littany of other "little" things can and will have a big impact on results. It is amber and clear and can vape with very little respiratory irritation. It came up in the only the strong thread, but lookin for a little more info. The picture was my ex-spouse. 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) 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. look in the CBD threads instead. Here is one techique that can remove any impurities soluable in water - specifically alpha pinene. Ended up a little dark so I ordered a gallon of hexane, warmed some up, and dissolved oil in it. About 5-10 minutes later the bubbling settles down so it looks like fizzy cola a bit with uniform and slower bubbles. 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. I get acetone from Amazon labelled as "Pure Acetone Nail Polish Remover" by the quart. Heating the diamonds through smoking or vaporization is the best way to enjoy the diamond's full potential and fast-acting effects. 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. Repeated washes from then on got a huge amount of the green out and fats and so forth. Cthis will preserve your terpene profile. 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 find that IPA cleans up dispensary extracts quickly, safely, and from this simple process I obtain nearly pure THC/CBN/CBD/ terpenes etc. Really icky goop in bottom of centrifuge tubes actually makes a good skin lotion that immediately softens my skin. But I've run a ton of washes through it and I'm still getting a gunk layer (only when cold) but the color of the hexane mixture isn't getting lighter or more yellow at all. We let it settlte and drained, it looked as if it was going as planned, the water was colored (but no percipitation). I have tested and it is nearly a one to one ratio by weight what the carbon absorbs - one gram of carbon will absorb one gram of material from your extract. You've picked yourself a challenge brother! More on hexane purging in the subsequent process description for serious scrubbing: To put this process into perspective, I once collected all of my pipe bowl scrapings and roaches until I had about a pint of them, and dumped that into the container of black denatured alcohol, that I had been cleaning my pipes in. Commercial n-hexane is a mixture of n-hexane isomers with a small amount of cyclopentane, pentane, and heptane isomers. Acute oral toxicity (LD50): 25000 mg/kg [Rat]. I noted above how it inhales. 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. How long/how many washes did it take to achieve this size rock? 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. The far more hazardous thing (verifiable with medical data) to do from a healhwise perspective is to kiss another human or share a joint or pipe. What am I doing wrong, can someone please help! com https://onlinecannamedshop.com. Two Dawns here Bro, I have a project that you need to be involved in ! correction - "condensation nuclei" (it has been decades since my meterology courses in professional pilot school), I'm pretty sure I get the picture, but question whether you do or not brother/dude/man, as well as your intent in wording your input. 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. For thin film evaporation, we place about .200 inch of it in a six inch Petri dish, which we place in a vacuum chamber and evacuate down to 29.5 mm Hg and ~80F for 30 minutes. TWA: 500 (ppm) from OSHA (PEL) [United States] Inhalation. Your wax is probably between 60% and 80% which is much better than pure stuff anyways (imo) because you get the full spectrum of the plant. Peace and good things to the Skunk Pharm! Could I just skip the first step of extracting from the plant material and evaporating that off just to re-dissolve in a solvent, and just go straight to salt water washing after the original extract from the plant material is in the acetone? Easiest to avoid extracting them in the first place by using subzero extraction techniques, but iffn you are stuck with a bunch, you arent dead in the water. 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. Winterizing ISO, Methanol, and Denatured alcohol extractions: Even though Ethanol is polar itself, it can still be used to remove some of the undesirables they pick up, because it is not as aggressive a solvent as Isopropyl and Methanol. We did our first experiment and the most unexpected thing ever happened - it didn't work out as expected, haha. You can get 95% grain alcohol shipped to your door at www.culinarysolvent.com. If symptoms such as redness or irritation develop, IMMEDIATELY call a . Ethanol however, is a very different story, being as I am in the UK and Everclear is not on sale here (nor do we have a limey equivalent). Place that dissolved mixture in front of a fan in an open container so the fan ripples the water. It has a burnt taste not normally present when vaped above 365F but is sweet below that. A rice grain size vaped into my Vapir 1 bag fills the bag twice with a dense foggy cool sweet orgasmic vapor. When you smear it on white paper, is it green or brown? Check the MSDS because the word light naphtha only means it boils between 30C and 100C, so it can contain Benzene.. That might be another solution. During this time, the THCa naturally crystallizes at the bottom of the container. I can't waste this material. The second time we washed, the water was lighter. My question here is can I use this method above to further remove the chlorophyl with white gas.. specifically Coleman camp fuel? . 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. When I clean up 80%-90% lab tested extract (mostly wax removal) with IPA I am left with extremely pure and pristine THC, which leaves nearly zero residue in my vaperizor. With iso it actually breaks the azeotrope between water and alcohol, forcing those two into seperate layers by themselves. Then run that through the column until dry and save it seperately. I added a bit of steam distilled terpenes to the top of the solution, to ensure stratification. slowly evaporate pentane untill desired saturation level is obtained you can check this by throwing a few test seeds in the pentane if they dissolve too fast you need to evaporate more if they dissolve slowly or remain their same size you are close. C2H6O(Ethanol) wil atract and retain H2O. From your post I assume you are also after THC. Maybe you could get patent on dust free extract and sell it and get rich - heck if you get rich enough even you might be President some day. It's not n, but it is HPLC. The water layer will be milk to chalk white. Inhale this dense vapor, and you might even talk to the Man on the Moon. Even at the hobby level for me it gets spendy to just evap it all. At room temp it is constantly decarbing judging by the experiments with time lapse photos up close to see it. I think together we can make it right . Chlorophyl is not soluble in water. This will remove approximately one-third of the remaining solvent. I wring the tea bags and am left with white waxy stuff and other solids. Hence floats on water. It is cheap, highly effective, safe, and uses just a Buchner funnel, vacuum pump, and the vessels to collect them in. In minutes it hardens into tiny air pocket ridden pieces. 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. Once you redissolve and have it at the saturation level thats desired, do you just pour that into the jar with the large seed? Rubbing alcohol is the label. So first you run 10%/90% solvent system. C. A vacuum of -15 to -20 mmHg should be used to assist the purging process. I notice lint in it. C over the course of 5-30 days. When performing your extraction, its important to chill your jacketed extraction system to -50oC or colder. By googling, I learned (contrary to my vast knowledge beforehand lolz) that some things, like iso and water, cannot be separated by distillation. We poured the soution in the separatory funnel along with 1 liter of saturated saline water. Be sure to use an approved/certified respirator or equivalent. The diamonds I had took maybe 10 mins to dissolve but its a noticeable difference. 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%. 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. It appears however that azadirachtin by itself is hydrobolic and miscible in water. Routes of Entry: Absorbed through skin. Have you considered extracting with something like Pentane, which you can recycle, and winterizing with ethanol? Make sure your work area is dust/contaminate free. Run the rotovap again. The relatively pure iso evaporates off much much quicker after the rubbing alcohol has been "salted down". Creating unique mixes from THCA is precise chemistry that will spawn thousands of future products. A personal disclaimer; I involve one more step that requires flame to volitize the remaining hydrocarbons out of the extract. 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. Less volatile means it'll be harder to remove.. I think this is why there is no simple answer to solvent questions because after all extract itself is solvent heavy (terps) and the ratios of the different solvents will always be a bit different.

I usually make a QWET into your HOA formula, batches of 1-2 ohzees per batch, and so I usually just add the coconut oil, cinnamon oils, etc. I have. Hope it helps. 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. EXTREMELY potent when captured in a Vapir party bag. Starting with the solvent and working our way to the crystal, lets explore the best methods to create the finest diamonds. The reason is that with a cookbook recipe we can be certain when we add flour, that the flour is as pure as it gets. But it's dark ! The good news is that if you are out of the stink or taste, you are less than about .01% of TLV, but the bad news (?) As the saying goes, the poison is in the dosage, so leave us please keep N-Hexane's potential nature in perspective, which includes never losing sight of it. bless up, #1 separate ht from hc And then repeat steps 1-7? The water layer underneath was clear. That is called a "Seperation Funnel" they come in various sizes. The extracts slowly leach out. The light yellow fluid evaporated down, and then I purged. CHILDREN IN INDIA ARE GOING WITHOUT!!! To further refine the THCA you can wash it in another hydrocarbon such as pentane to try to remove the remaining . Once unwanted seeds form remove.
