washing diamonds with pentane
Absolutely. How or can I at all remove neem oil from my bho? Ostensibly Methanol would do an even better job winterizing, but would require tighter purging standards. Thanks for your efforts. at a certain point the polarity will become just right for the cannabinoids to pass through the column. I modified the screen a bit to accomodate extract. About 2-3 inches. Vapors are heavier than air. I have found the following site to be a good source on information on this sort of thing. What evidence can you provide that suggests the lungs are not capable of dealing with this? The water layer will be milk to chalk white. Also, when mixing multiple solvents into extract it can be a pain in the rump to purge them out, and forget about recovering the solvents lolz. I don't think it matters as far as protocol, you'll just need more heat and time to remove the heptane once you're done with the wash. People use butane/propane because of its low boiling point, not because it's safer. mandurah news body found Login. 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. nope. May Life not life on you too often. I placed ~2-3 grams of extract in a 20mL GC vial. GW. I put the dispensary extract in a couple of tea bags. Sigh. Here is a very short version of what I do to make my Pristine Oregon Pharmers World Class extract into a product that is vaguely fruity, makes DENSE foggy vapor, has zero, nil, no, and absolutely zed respiratory irritation even when held in a long time. #8run dissolved liquid into coffee filter back into a clean jar this is to prevent unwanted seeds from starting, #9(room temp) During this time, the THCa naturally crystallizes at the bottom of the container. 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. This will remove approximately one-third of the remaining solvent. The smoke is horrible so I don't believe any THC is left at this point. 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). Metal-organic frameworks (MOFs) are highly nanostructured coordination polymers that contain metal cations and organic linkers and feature very large pore volumes and surface areas. An easy way to get rid of them is to simply re-dissolve the non-polar extraction in 190 proof (~95.5% azeotropic) polar ethanol and stick it in the freezer for about 48 hours at -18C/0F, for the waxes to coagulate. I pre-heat my oven to 250 F. I put the iso/extract mix now onto a preheated cookie sheet. yuck. Fire Hazard 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. So first you run 10%/90% solvent system. Oops! My first step is adding roughly 60g of BHO to around 24 oz of Klean Xtract. or not? In my attempts to polish with hexane I have done the following: Filter is "slow" rated for fine crystals. I have done this several times and it works but is not activated carbon. I just cannot manage to get it to become a shatter consistency. Gloves (impervious). Get the picture? I better wrap it up now.I have a bag that is just waiting for some vapor. It's not n, but it is HPLC. If it works out (it should) and we go that route, we'll need to preserve half of our flowers in some way, enabling us to store them away securely so we could process one halve now and rest later. Run the rotovap again. We are working with oil extracted through warm methanol extraction. Once the extraction has a syrupy consistency, I use a vacuum chamber to purge off the remaining alcohol, and this is where things get complicated. Gently wash all affected skin areas thoroughly with soap and water. If not, there's your problem. Hazards What is this information? I noted above how it inhales. The extract shown certainly contains terpenes. The reason we are trying to yield pristine oil is so we could advise accurate dosage to our patients as the medicine is illegal here and no lab testing is available. GW. What it takes to repeat success is a commitment to observing carefully and closely. When in the seperatory funnel in conjunction with hexane and iso I have seen odd seperations happen. They contain both the undesirables, and the alcohol as well, with the cannabinoids left with the hexane. Perform your extraction as normal but maintain a ratio of solvent to biomass between 6:1 and 10:1. 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. For the final time, all of that goes back in the rotary evaporator. I reasoned that the RSO had been ethanol extracted soxhlet style, so guess that ethanol was present. The issues I am having is that I do not get a distinct phase separation between the water, emulsion and hexane layers. 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. Put the filled dish and crystallization vessels into a vacuum oven using a drying temperature between 18-30oC. I just scanned through the site and it doesnt look like Joe ever published his chromatography results, so Ill publish something using a picture of his samples, to explain the issues with color and other non-targeted elements. 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. Step Two: I load my raw extract into a ceramic cigarette. We think reducing it 10 to 1 or 2 should be safe. 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 have recently made nearly pure thca powder in my cls by accident. Repeated washes from then on got a huge amount of the green out and fats and so forth. If it is not chalk white, evaporate and oil will be recoverable. Any ideas? Hey skunkpharm! - Do we really need salt in the water? I was only given crude to do R&D with so every time I would get some id isolate the thca and add it to it, Nice! 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? Take a puff and it will knock your socks off lolz. 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. Combining THCA with cannabinoids like cannabinol (CBN) and terpenes that promote relaxation, such as linalool, could assist in recovery or rest. Plus remember that "Hexane" is not the name of a particular chemical but names a group of chemicals with substantially the same characteristics. Processes that use a polar solvent and reflux or soxhlet to maximize extraction, also maximize and concentrate chlorophyll, which can be a problem for some people. GW. https://vimeo.com/172564716, I really like what you guys are doing. On Dec 13, 2016 8:46 AM, "Skunk Pharm Research LLC" wrote: Then I quickly turn the glass to vertical, and the part of the puddle that is "runniest" flows down a short distance as a "drip". When you are cleaning up really gunky stuff it might be more practical to use 10% increments. It always tends to leave traces and crystals in the extract thank's for the information. N-Hexane boils at about 69C/ 156F and has a high vapor pressure, so it is easy to evaporate, but harder to completely purge. When you smear it on white paper, is it green or brown? Get some integrity already Second, I let the substance dissolve around 80 degrees, with some agitation. Thanks. Shake well, stick it in the freezer fro two days. Recover most of the solvent, or about 90 percent, at 18oCthis will preserve your terpene profile. the first trip through the flame it is quite a light show. 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. 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. One thing I notice is it takes quite a long time for bubbling to become visible. Next month I plan to do a vid from start to finish and present the results in a video to show it. DCVC has a few KEY advantages over this but is substantially the same idea. I can't waste this material. The mix will clearly seperate into multiple layers. Control Parameters: 109-66-0, Pentane, NIOSH TWA 350 mg/m3 109-66-0, Pentane, ACGIH TLV TWA 600 ppm 109-66-0, Pentane, OHSA PEL TWA 1000 ppm Appropriate Engineering controls: Emergency eye wash fountains and safety showers should be available in the immediate vicinity of use or handling. Good luck. #11 if small unwanted seeds start to appear over time isolate wanted seeds repeat step #7 and up Same concept applies to pentane vs heptane. At room temp it is constantly decarbing judging by the experiments with time lapse photos up close to see it. One article cannot cover the multitude of variability encountered in our pursuit. 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. 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. Bleed off bottom layer (or what I can semi distinguish as the aqueous phase) and replace with clean water. When I helped a friend yesterday to clean up RSO into THC oil (REALLY messy lolz), we started with a hexane/water wash. At first there was no visible seperation visible which should not be possible, right? It is the azadirachtine that is reported to have the strong odor. If an extraction auto-budders on me, I tend to use an ethanol wash with Klean Xtract. We haven't figured that one yet. Set aside and come back in 1/2 hour. This step isn't essential, but it did seem to help. The oil becomes hard and taking the dish out, the water left melts first abd pours off easily. Ever try winterizing at -80C (or anything lower than 0?). In my experience, the level of pressure and temperature dictates the type and size of crystals you achieve. A personal disclaimer; I involve one more step that requires flame to volitize the remaining hydrocarbons out of the extract. The described process is called diamond mining in the recreational market. I doubled the hexane from 100ml to 200ml total and voila! Ended up a little dark so I ordered a gallon of hexane, warmed some up, and dissolved oil in it. This is because every extraction can be different. So put in a large seed. If you have a dewaxing column, you can utilize this to assist in further removing undesirables. 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). This is our main concern. Hexane is as easily recovered as Ethanol, using the same techniques. What would your recommendation for maximizing the yield be, without doing a warm extraction? Any tips or suggestions would be great! ISO wash done at room temperature, overnight. Another vape hit. Thank you for sharing such wonderful information. Only tiny bits of immiscible particules. My procedure is as follows: Question regarding Ethanol purging: I notice lint in it. The layer that is amber and clear is the good stuff. The reduced yield is not as much as you might think, once you eliminate the non targeted element pickup. i will guarantee you will end up with a nice amber color oil high quality oil. In meterology this is called "condensation particulate" and dust was once added to clouds in an attempt to seed the rain. After I notice no bubbles forming (15min - 1 hr), I pressurize the chamber and pull a second purge. Do you have an email graywolf? This is only needed to be done through about 2-3 inches of alumina and is done under vacuum which is opposite of flash chromatography done under pressure. 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%. You seem to be blissfully unaware that we don't sell any concentrates to anyone, period. No matter how hard I dry the the ethanol, the pastiness exists. @mylkingtrees Ummm dude3, hes referring to the filtering funnel on top of the bottle @Guapo sir the pirce of labware that you are refferring to and that this man is faiiling to correctly inform on is called a "Buchner Funnel" It is usually used in conjunction with an "Erlenmyer Flask" with a vaccum port feature, a filter paper is placed in the filter funnel an a vaccum is applied to the port on the flask, when filtering flow slows down from a clogged filter, vaccum is turned on to assist in speeding up the process. Attached are pictures of the amber oil that I extracted. 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. I have been tasked with helping a producer in Oregon who extracted with isopropyl alcohol to clean his stuff up as well as several various batches over time from others who extract with SCF extraction methods. The hexane layer was dark but the layer underneath was light yellow We use premium flowers - the quality is certainly there, still, we are hung upon being able to advise accurate dosage. 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. Anthrocyanin plant pigments are one of the prime culprits, and are about a ~C-30 molecule, in the same range as chlorophyll and plant waxes. 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. The following is a typical MSDS Section 8: http://www.sciencelab.com/msds.php?msdsId=9927187, Section 8: Exposure Controls/Personal Protection. Rubbing alcohol is the label. Trying to turn small diamonds into bigger ones. It turns out that I don't mind or notice a bit. We are way over budget and we thought this would be the cheapest way to achieve high yield with one wash. Same with the eggs and so forth. Excellent post, we'll definately look into this in the future, sounds quite interesting. Excerpt from NIOSH Pocket Guide for n-Heptane: Eye: IRRIGATE IMMEDIATELY - If this chemical contacts the eyes, immediately wash (irrigate) the eyes with large amounts of water, occasionally lifting the lower and upper lids. 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). The darker colors are typically the C-30 size molecules like anthro cyanin plant pigments, which are also glucosides (plant sugars) and can darken with caramelization. It also takes longer to work the emulsion layer with subsequent washes, and each wash leaves with some, so at some point need to make the call. Insert a pipette with square tip into the bottom of the test tube (rounded bottom), and remove the liquid, leaving the washed solids behind. C. A vacuum of -15 to -20 mmHg should be used to assist the purging process. It will reach that pointI nearly soiled myself once learning about oven doors exploding to the open position Redissolve. 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. Rubbing alcohol that I recomend trying would be a 70% isopropyl alcohol to 30% water ratio. The sorption and desorption of n-pentane vapor by porphyrin aluminum metal-organic framework Al-MOF-TCPPH2 where TCPPH2 is tetrakis(4-carboxyphenyl)porphyrin linker were studied by a novel method of in-situ . Wash using a pipette: used for small amount of crystals to be washed. We've got a bulk quantity of medicine that we would like to polish. Dale talks about fighting to free cannabis prisoners, staying active in cannabis advocacy, and reducing the stigma around the plant. Once that's done, seal the concentrate in a container and leave it for two to three weeks. Loved the question part at the bavk also, very educational. Do you happen to have pics of your end results using this tek? Perhaps tongue in cheek, but I am more or less making fun of the paranoia we have in using chemicals with tech names, when in fact we ourselves are just a bunch of chemicals. For some reason, my alcohol, Hexane and water mixture does not bringing chlorophyll down. I don't have access to butane, I am pretty much a double-boiler type QWET setup (NuWave w/candy thermometer for the cooking oil, stainless steel 2 cup UKonserve container for the mash/oil). This low and slow method will encourage more nucleation due to increased temperature and pressure and larger crystal growth. At this point, I have concentrated it down to a very potent, yet very dark matter. 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. 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).
