Your "pasty mess", from your description is H2O still in your Onion. There are limits to what you can wash out with brine and if you have a lot of chlorophyll, it isnt really water soluble, but washes away in micelles, so it doesnt come out easily. I notice the first pull down to -29.5Hg lets the extraction boil off very rapidly, then slows to a crawl. . Can the solution just be left to air dry for several day's?, or do I need to 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. When heat goes above about 350F and held there then some bad odors and flavors develop in all the strains I have tested this way. Pour off mix into seperatory funnel. Growing cannabis is a fun and exciting hobby unless your plants produce less flower than you had hoped. *A strainer works well for seperating the rather pure thc-a from the chunks Boiling point 97F. While THCA is a useful cannabinoid on its own, the synergistic effects of cannabinoids and terpenes are not to be underestimated. N-Hexane boils at about 69C/ 156F and has a high vapor pressure, so it is easy to evaporate, but harder to completely purge. I have done a LOT of seperatory funnel work, centrifuge work, filtering, cooking, distillation, and have even oxidized away Volitile components of extract with Hydrogen Peroxide by carefully creating an emulsion of extract at elevated temp with (drop by drop) 35% food grade hydrogen peroxide. THCA diamonds can be created from any non-decarboxylated cannabis oil, whether its crude oil made from trim or live resin oil derived from fresh frozen flower. Acute toxicity of the gas (LC50 rat): was 48000 ppm using 4 hours exposure data and the Threshold Limit Value for an 8 hour weighted average in breathing air is 500 ppm with a Permitted Exposure Limit of 1800 mg/M3 (~ppm). Below 10 degrees celsius, outdoors, not frozen 90 seconds wash. 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. TWA: 1800 (mg/m3) from OSHA (PEL) [United States] Inhalation TWA: 176 (mg/m3) from ACGIH (TLV) [United States] SKIN TWA: 50 (ppm) from ACGIH (TLV) [United States] SKIN TWA: 500 STEL: 1000 (ppm) from ACGIH (TLV) [United States] Inhalation TWA: 1760 STEL: 3500 (mg/m3) from ACGIH (TLV). Because butane is non polar and considered insoluble in water, it is the longest chain alkane that is still slightly water soluble at 0.0325 vol/vol (3.25%). I accept the danger in my own kitchen and simplyhave not found a way to finalize the polish without it. Less volatile means it'll be harder to remove.. For some reason, my alcohol, Hexane and water mixture does not bringing chlorophyll down. If they are growing slowly this is the ideal saturation level. If you intend to produce a THCA crystalline with above 99 percent purity, you will need to perform these washings. When you say acetone/water experience, is this including salt water? The resulting RSO concentrate is a dark harsh wax/tar (50% THC). Micro filtration is the same thing, but uses a larger pore size, so might not clog as fast and I've installed industrial plate and frame micro-filtration plants down to 0.2 microns. GW. It takes a LONG time for the decarboxylation to occur doing this judging visually. I realized I need to stop putting the eventual "carrier" type materials right into the just-finished cannabis oil while it is still in the mash container - that will keep me from having to salvage anything in a polish maneuver. Hi, Cheers. I hope all this helps. Light smoking will occur if particulate is present - the goop oil will stop smoking though. 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. Neem oil with azadirachtin has been given to children orally in the Far East for various remedies for a very long time. The amber, by the way, becomes pretty tough in consistency. and put your freezer at the coldest temperature ) Next step is to add your alcohol to your plant material , buds, sugar leaf whatever you are using and place back into the freezer for another 24 hours , during this time shake,or stir occasionally.Step 2: use cheesecloth or bleached free fabric to filter your plant material& alcohol, once this is done place alcohol oil mix back into freezer and discard plant material. Because it is a simple Alkane and relatively non toxic, hexane is used extensively in food extraction, but should not be viewed as being as salubrious as mother's milk. Heck, I even get little gnats that land in it. We are willing to consider changing the solvent, however, even with lab grade methanol at this price (cheapest solvent) we are struggling financially Time is an additional constraint in that sense. After this time, remove the vessel from the cold environment, open the vent valve, and allow the solution to reach room temperature. Kleen xtract has been the wash to get it back into a "purgable" consistency. Individuals with nausea may want a capsule or tincture that has a ratio of THCA and cannabidiol (CBD), another cannabinoid with potential anti-emetic effects, and some myrcene to help alleviate their discomfort. Removal with a pipette or eyedropper. Thank you sir or miss! 2) THC does not significantly break down with the application of extreme heat so long as oxygen to oxidize the THC is present. What the meaning of "treated with ether and water after cooling"? 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. With each solvent gradient the column progressively elutes the less polar compounds. I will post pics of my crystals when they are bigger. Sounds like a ploy.. Adding salt is not productive at all because it iterferes with the water in a way that prevents the water from pulling pinene out of the goop. I have used acetone in combination with hexane and isopropyl alcohol, as well as used it to great effect in cleaning my hobby lab glass. Your time is always much appreciated, Skunk Pharm. Reddit - Dive into anything I have not included the full details as I have been asked not to discuss this in this site for safety reasons. As you may know, anything above 15 is considered polar, with water at about 80. It works without question and the only product loss will be the polar compounds which will not pass the alumina column. The most dangerous thing was not consuming cannabis, it was getting caught with it.. Will this work? He is surprisingly open to conversation. What were your perameters for that thing?! 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. Garden. Prior to centrifuge I would place the tubes in my freezer which is set to lowest temp. Hm! I get acetone from Amazon labelled as "Pure Acetone Nail Polish Remover" by the quart. If you have a dewaxing column, you can utilize this to assist in further removing undesirables. Oops! Combining THCA with cannabinoids like cannabinol (CBN) and terpenes that promote relaxation, such as linalool, could assist in recovery or rest. I suggest that you start with a small sample and see how it works for you! I have done many experiments with hexane, acetone, alcohol, and ethyle acetate as well as water. 3.25% by volume is also enough water to bring along some water solubles like chlorophyll and leave an otherwise pristine extraction with a green tint, usually light and sometimes a gorgeous electric hue. Once the desired diamond size is achieved, pour off the remaining layer thats comprised primarily of terpenes. It is a sort of thin film chromatography separation and works surprisingly well for seperating the components of an extract. Hey skunkpharm! 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%. I take the glass which is cool to the touch and dab my goop (wax or shatter or scrapings) onto the glass which is held horizontal. Looks like a 1000 ml Sep they are using in the photo. > redturtle984 commented: "It is not correct to say that using hexane is not > highly effective at recovering thc from any form of extract. What I just typed is how I would attempt it. I might have to drain the bottom layer off a frw times as I do this. you will dissolve more thca than wanted So waiting for the rubbing alcohol to evaporate or not having any rubbing alcohol present, I will tell you another sure fire way to "clean up" small amounts of wax and shatter; hehe. Here is a link to a DIY evaporator that addresses that issue. No matter how hard I dry the the ethanol, the pastiness exists. Provide exhaust ventilation or I can think of a lot of things I would like to have extract from. If you have time to talk I am keen to learn more and would love to start a rappor with one of my idols. Without testing you cannot know these answers. Tattered old wolf, Either ethanol or methanol have the same issues, though the dielectric constant of methanol at 32.7, is higher than either isopropanol at 17.9 or ethanol at 24.5, so is more prone to extract polar molecules like chlorophyll. #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. Step V : Here's where the chromatography machine comes . Was thinking this may be a good experiment but I think the main impurity is oily so would probably migrate to the hexane layer. Are you using 70% ISO, thus taking advantage of the containment of water to dissolve the salt? Do you happen to have pics of your end results using this tek? My extract begins to decarb noticably with very little heat. We've observed that when evaporating 1 liter of methanol, hash oil starts forming in the last 50ml. That might be another solution. 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 . Boiling point (at 760 mm Hg): 68.9 degrees C (156 degrees F) 3. The MSDS sheets regarding the inhaling of terpenes says do not do it, yet people do it all the time and many believe it benefits them. Nice and cheap is great! look in the CBD threads instead. You can purchase these on Amazon. I better wrap it up now.I have a bag that is just waiting for some vapor. Thank you so much! Turn on stirring and turn on the heating bath and set to 45 C. The water layer underneath was clear. I just cannot manage to get it to become a shatter consistency. CHEMICAL AND PHYSICAL PROPERTIES 1. Then the bottom portion can be removed through the bottom port. The resulting black gunk can easily be purified/purged much further until it is deep red (normally). What would your recommendation for maximizing the yield be, without doing a warm extraction? Excellent post, we'll definately look into this in the future, sounds quite interesting. Perfect for separations like this. 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. There wasn't really enough that precipitated out to smear onto paper to see. 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. These light green hues are easily removed without the more involved and extreme measures that I will follow up with, and is as simple as putting a jar of the oil suspended in an ethanol tincture, in sunlight or a light from a high UV source, like a grow lamp. Then, reduce the pressure in your system to -30 mmHg, or as low as you can go based on elevation, using your vacuum pump. This is VASTLY more than our senses will detect, and is also VASTLY more than most bodies will ingest before violently regurgitating. It had 1/2 dram of LorAnn raspberry flavoring in it (PG, color, flavoring). All I used was a 1 micron paper filter, DE and pentane. For our in house information, we picked up our own gas chromatograph used for $12K. Hexanes dielectric index is closer to 1.3 and for all practical purposes, isn't miscible, so I thinking not. On another note, we are not that sure anymore about complicating the situation further with additional processes. 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.
