We would be happy enough If we found a way to test the potency of our extract. Soooo, what if the extraction is really, really messed up, or if you just want to see how purdy you can make an extract? 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. Now remove from freezer, work it cold, and filter the fluid. 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. Pentane is a highly non-polar, light hydrocarbon solvent, that acutely dissolves THC instead of plant matter. Would have a question for you. Otherwise the drip is a bit milky with wax and harsh. So am I missing it or did you not publish something using pictures of his samples? Be careful, though, as too much solvent or solvent that is too warm will dissolve your THCA. Some MMJ applications require greater purity and potency, so it is desirable to remove inactive ingredients like fats, lipids, and plant waxes, as well as any chlorophyll and other water solubles. Pentane and Heptane are Class III solvents with FDA residual solvent limits of 5000 ppm: Hexane on the other hand is a Class II solvent with limits of 2.9 mg/day and 290 ppm residual. Any tips or suggestions would be great! add pentane (-20 -50c seems to work best) too cold and you wont dissolve undesireables too hot you will dissolve too much thca .too much pentane will dissolve too much thca as well , too little wont dissolve enough I do the same if I am making vape oil - I use a PEG mix (EJMix, lower temp for most of the purge of course), and add a little flavor, all right in that mash container. Hexanes dielectric index is closer to 1.3 and for all practical purposes, isn't miscible, so I thinking not. GW. Washing Diamonds: There are a few ways to go about this. Removal with a pipette or eyedropper. I have done many experiments with hexane, acetone, alcohol, and ethyle acetate as well as water. The section for Gerbils and Hamsters has syring type eyedroppers for feeding medicine and test tube size tubes with rubber stoppers and a hole in them for watering the rodents. 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. I need help!! Was looking for more info on dissolving an recrystallizing in pentane. My hunch is that environmental factors like ambient temp, the times of reaction involved, and maybe even a dirty seperatory funnel may have been factors I could not duplicate, and the fraction that I described was only a small percentage of the THC I recovered from the hexane layer so I did not try more than a few times to repeat the idea. Here is a link to a DIY evaporator that addresses that issue. other than the diamond you are focusing on. Use a fan to evaporate off the alcohol (about 15 minutes) then place the almost dry extract on some cooking paper. Extremely potent this way, likely owing to the possibility of DEEP lung inhalations without coughing. Sometimes bad things happens to good oil, and evil spirits need to be exorcised, or sometimes the most economical process, or indeed the only available extraction process, extracts undesirables. This doesnt mean it isn't effective it just means that more understanding is gained with each effort. 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. illustrated walkthrough of doing a hexane wash (Cannabis) 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 Even at the hobby level for me it gets spendy to just evap it all. Get some integrity already Based on this, my "go to" method of removing the irritant azadirachtin would be to attempt to disolve it in water. Oops! A vacuum of -15 to -20 mmHg should be used to assist the purging process. Eventually the oil wil seperate from the alcohol in the seperatory funnel as fresh water is added. After it has separated, bleed off the water and emulsion layer. I captured it and it was acetone (smell). Check the MSDS because the word light naphtha only means it boils between 30C and 100C, so it can contain Benzene.. The oil will stick to the dish. less than two busks and the have a clip to hold them vertically. Repeating the last two paragraphs of the article for your benefit: 10.9.1 Diamond Mining by Erich Berkovitz - GrayWolf's Lair When you smear it on white paper, is it green or brown? Instead of predicting results, it pays to observe the results and learn the "little" things that happen and use "common sense" (taste, touch, smell, look, sound) to figure out how to adjust. The oil becomes hard and taking the dish out, the water left melts first abd pours off easily. This HTSFE is comprised of high potency THCA crystals with a layer of terpenes. This one ended up a little over 100g, took maybe 10 cycles ? I put the dispensary extract in a couple of tea bags. Link to a pdf of the issue, Previous Post: Faculty Feature: Anthony DeMeo. As the mix evaporates off there is typically a milky white seperation of two immiscible layers that develop. Skin: SOAP WASH PROMPTLY - If this chemical contacts the skin, promptly wash the . 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. And then repeat steps 1-7? Invalid username/password. I tried this with some older trim that was run with butane. Also, we need to process our entire batch before proceeding further This new vid I made this morning boils the extract and also makes the water a bit murky. I use a rod in the lip end to plug the cigarette and to hold it comforatbly from the heat. Step Four: I light the lighter and slowly allow the exrtact to run into the flame and drip down through the flame onto the glass. Sorry, we don't have an account for that email. At that point we stop washing and evaporate off the hexane. You will have to come down to Nor Call for a little while It didn't dilute very easily (???). Or please point the way to where I might be able to purchase the same one? Part two. I have never had any evidence that an acetone/extract mix can be "washed" with water. - Should we 'winterize' before washing or that is not necessary? The different chemical weights and properties seem to make them separate into distinct layers as the iso/water mix resolve into different layers (water on bottom). When using non polar solvents like butane and hexane, some non-polar waxes, fats, and lipids are extracted as well. Repeated washes from then on got a huge amount of the green out and fats and so forth. 2) THC does not significantly break down with the application of extreme heat so long as oxygen to oxidize the THC is present. I pick the pieces off with frozen tweezers. I'd add 3 parts distilled water to 7 parts Isopropanol from my material wash and just follow the same process for salting the water out once i'm done, repeating until I have to use the refractory index of the two fluids to tell them apart and look for that visible layer yea? 95% thca cristals are white. We feel the purity of our medicine would be irrelevant considering there are no alternatives due to tyranical laws. From your post I assume you are also after THC. 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. 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. First off ,freeze your alcohol and plant material separately for a good 24 hours ( never wash at room temperature! What Are Weed Diamonds? - MERRY JANE The video demonstrates my modification in that I force a separation at a 50% mix of water to iso. All help is appreciated, as the chlorophyll is making my medicine give me a headache in place of relieved leg and back pain. I use 5% increments as an example. That means that a liter of n-butane will actually hold as much as 32.5 ml or mgs of water (1000ml X 0.0325). It was nearly pure THC, sweet chalky flavor and delicious. It can however, be fractionalized by adding salt. The end product can be incredibly flavorful and potent, and many dabbers who prefer live resin also prefer the crystallization of "terp sauce." . Each time you pour off the terpene layer and leave the crystals behind, the potency increases. Silica would likely work great but comes with a few problems regarding toxicity when inhaled, plus very tiny percentage will disolve in isopropyl alcohol and end up in our sample. 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%. Just using acetone/salt water is unlikely to work, and 2. We are working with oil extracted through warm methanol extraction. The picture was my ex-spouse. I filtered the hexane and poured that into a Pyrex pie plate, which I blew air over with a fan to evaporate off. Rubbing alcohol cannot be separated by distillation - the water and alcohol won't separate that way. Good luck. Lab coat. I scraped it up and vaped it and honestly couldn't tell the difference at all. Signing up indicates your consent to our Terms and Conditions and Privacy Policy. Then, pulverize/blend into a fine consistently. I generally see the best results going from the most non polar solvent (hexane) and proceeding towards the least polar solvent one step at a time in the seperatory funnel. N-PENTANE | CAMEO Chemicals | NOAA The hexane was much brighter, but when we purged, it came out pretty black. Some even contains a dye. Join the Movement.Sign up to receive email updates for more opportunities like this, cannabis job postings, events, and more. Set aside and come back in 1/2 hour. Thanks. When held to the light the drip part of what remains is clear and amber. It's a syringe that wont hurt a mouse lolz! In my humble opinion, you are doing it absolutely right. Acetone is polar with a dielectric index of about 20.7 and is miscible in all proportions with water. Extract washed this way dispenses with the mediciney "Metholatum" taste. Ideas are more than welcome! I stuff it in there real tight. 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. Repeat this in 5% increments until the system is 100% isopropyl alcohol and you will be left with 20 samples. We used around 8 liters of water and 3 liters of methanol. ( depending on your material and type of alcohol you use). I'm wondering in regards to using UV light, if Sylvania UV-Lamp 400W E-40 would be of choice or is it too powerful? Easy to visually identify each substance mostly by color this way. The web says PAM is water soluable. Step Five: repeats several times. Can anyone suggest me an effective method for the - ResearchGate 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 Besides name calling your post has little data to support your claim that environmental elements found in normal day to day living are hazardous beyond the hazards already present in the product. 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.
