washing diamonds with pentane
I use 5% increments as an example. What would your recommendation for maximizing the yield be, without doing a warm extraction? It is carried by it like a boat is not soluble in the stream it. It occurs to me that marijuanna is often grown outdoors as well. A vacuum of -15 to -20 mmHg should be used to assist the purging process. If symptoms such as redness or irritation develop, IMMEDIATELY call a . Can neem oil be removed from butane extracted bho? *A strainer works well for seperating the rather pure thc-a from the chunks After shaking it well, I hung it from one corner, to let it stratify, and after it had, I clipped off the lower corner of the Ziploc bag, and by pinching it, and controlling the bleed rate, I was able to bleed off the water, alcohol, and emulsion layer, so that only the now gold hexane solution remained. I notice the first pull down to -29.5Hg lets the extraction boil off very rapidly, then slows to a crawl. Following this I dissolve the winterized oil in n-hexane (Ratio 20 g ISO to 100 ml hexane). We used 20 grams of oil and around 200ml of Pentane & Hexane mix. Im assuming 7-10. This means it is designed to sublimate frozen water into water vapor, skipping the liquid phase. D. Gold. Take a puff and it will knock your socks off lolz. Be careful, though, as too much solvent or solvent that is too warm will dissolve your THCA. 95% thca cristals are white. I like iso because it falls in just the right niche polarity wise to target the medicine. Seperation with a definate emulsion layer between. The following is a typical MSDS Section 8: http://www.sciencelab.com/msds.php?msdsId=9927187, Section 8: Exposure Controls/Personal Protection. I have some Everclear. Experience has proven to me that this is the moment to stop heating it and put turn it up for the drip to form. Below 10 degrees celsius, outdoors, not frozen 90 seconds wash. Prior to centrifuge I would place the tubes in my freezer which is set to lowest temp. In the video I am processing extract into a more refined product which I vape happily, and the video starts as the centrifuge of the isopropyl alcohol and extract mix are finish slinning the waxes out. Thanks 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. Absolutely. Good luck. Was looking for more info on dissolving an recrystallizing in pentane. I can even take the extract so cleaned up and when placed on a cool glass surface can seperate the components easily with a flame above the goop and a tilt to the surface. 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 . Part two. 5) Spin the tubes at 4000 rpm for 20-30 minutes. I ensured the solution was supersaturated by adding small amounts of BHO into solution, until no more would dissolve at room temp. If anyone has any knowledge of how this problem can be fixed, it would be greatly appreciated. Light smoking will occur if particulate is present - the goop oil will stop smoking though. Here is what I would do with a glob of black tar as you describe. Place in freezer. How or can I at all remove neem oil from my bho? I have found the following site to be a good source on information on this sort of thing. It has a sugary crystalline structure, but is opaque in appearance due to high terpene content. Hexane and water do not mix. Invalid username/password. Hence floats on water. 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? When performing your extraction, its important to chill your jacketed extraction system to -50oC or colder. do a vac purge? Here is a short video of the finished product with no solvents being shown burned off. They melt right in and are very pleasant to the touch, though they are highly irritating to the eyeball so washing hands is a good idea after rubbing it in. What were your perameters for that thing?! 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. 6) The seperatory will reveal at least two layers and in the first stage sometimes a third. If we wish to filter it further, we run it through 0.45 or 0.2 micron syringe filters, which takes out any remaining plant material, as well as any bacteria present. Sigh. My plan is to just keep doing this to see if they continue to grow. Based on this, my "go to" method of removing the irritant azadirachtin would be to attempt to disolve it in water. 3 yr. ago. Very interested in being able to remove as much amber color as possible. 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. Clarified neem oil is food stuff - lipids and fats. 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. This time, a lot of stuff percipitated. might be a little off but it will at least give you some starting points . This will yank out the rest of the isopropyl alcohol and nab some water bubble too likely. 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. Get the picture? Trying to turn small diamonds into bigger ones. 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. We are working with oil extracted through warm methanol extraction. Powered by Discourse, best viewed with JavaScript enabled, https://future4200.com/search?q=CBD+pentane. It works for cleaning extract up. 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? 3) After nap, I would vape some good oil, then, after cooling I would disolve the goop from the oven in a mix of 70% isopropyl alcohol/30% water (rubbing alcohol). How long should i wait before the ethanol is gone, always seems to have a slight smell to it. #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. Make sure your work area is dust/contaminate free. That long process results in 99.96% THC. How long a quick wash at what temperature? 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'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? It works without question and the only product loss will be the polar compounds which will not pass the alumina column. The goop will run down the cool glass and become solid as each component in the goop cools to the point of this phase transition from liquid to solid (more or less). It helps purge the residual butane. I use isopropyl alcohol and water as a solvent system because it is inexpensive and much safer from a fire hazard and fume point of view than systems that use hexane. You can get 95% grain alcohol shipped to your door at www.culinarysolvent.com. I filtered the hexane and poured that into a Pyrex pie plate, which I blew air over with a fan to evaporate off. This is my sop (without getting into minute details) it really only is efficient for 100+ grams of thc-a otherwise there is a significant loss The resulting RSO concentrate is a dark harsh wax/tar (50% THC). ! We deeply appreciate your support and what you do! Since purity is already so high and it is in crystalline form this should be relatively easy given the correct procedure. 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. Amber black 4 months old. Once that's done, seal the concentrate in a container and leave it for two to three weeks. http://www.collectioncare.org/MSDS/naphthamsds.pdf This low and slow method will encourage more nucleation due to increased temperature and pressure and larger crystal growth. 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. Any ideas? It's not n, but it is HPLC. Hey skunkpharm! How dry is it? Coleman's MSDS identifies it as light naphtha with a boiling point above 100F, so check out a typical light naphtha MSDS also attached. keep pentane in liquid state if becomes oil like viscosity add a small amount of pentane too much and you will dissolve thc-a too little and you will not be dissolving the unwanteds anymore What am I doing wrong, can someone please help! The light yellow layer mentioned with acetone evaporated into pure thc judging by the slightly sweet chalky flavor and my commitment to solving Einsteins problem with gravity as a constant in any given inertial frame after vaping some. :). I remove the liquid with a vac chamber but how do hou keep that sample from decarbing? After this time, remove the vessel from the cold environment, open the vent valve, and allow the solution to reach room temperature. If I can ever help in any way, let me know. 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. Please try again. Hi, If an extraction auto-budders on me, I tend to use an ethanol wash with Klean Xtract. I rarely use flower because I do not extract, but this reply is in hopes of helping you out. At the end of this process, you will have produced a high potency THCA diamond. Once the vessel is filled, tightly close and chill it to -75oC or colder for 48 hours. For some reason, my alcohol, Hexane and water mixture does not bringing chlorophyll down. The flow keeps the filter membrane swept clean as it passes through, so the flow concentrates and the clean stuff weeps through to the outside. Thank you sir or miss! 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. I have tested a multitude of solvent/lab techniques to accomplish what you are attempting. Bottom line, all this hexane method. Ive already noticed tiny crystals (the size of turbinado sugar crystal) forming on the bottom of the vial. Then the bottom portion can be removed through the bottom port. Next month I plan to do a vid from start to finish and present the results in a video to show it. THCA is white when pure (or close to pure). Shatter consistency is caused imo by impurities in the extract. I find that IPA cleans up dispensary extracts quickly, safely, and from this simple process I obtain nearly pure THC/CBN/CBD/ terpenes etc. Link to a pdf of the issue, Previous Post: Faculty Feature: Anthony DeMeo. btw 98% is completely false. Next Post: Faculty Feature: Stefanie Gangano, Ph.D. How to Get the Most Flower Weight from Your Cannabis Grow. When you smear it on white paper, is it green or brown? The mind change is unmistakable. Finally, after 5 hours of washing and waiting for the layers to separate well, we gave up. What is left, is "Absolute" Onion extract. #10 add big seeds( at this time your saturation and purity levels should be ideal.) 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. I handle the oil using a medicine feeder for rodents I got at Petco. does not really works, am I understand it morrect? Check the MSDS because the word light naphtha only means it boils between 30C and 100C, so it can contain Benzene.. Repeated washes from then on got a huge amount of the green out and fats and so forth. I'm looking for an older link you posted to terps you bought off line. When you say acetone/water experience, is this including salt 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. Did you actually read the article, or just look at the purdy pictures? The real question, putting aside your personal attack, is this; "What data do you have that suggests the dust or debris that might collect in your extract is harmful to human health vs. an advantage to human health? Put back into freezer for a couple of hours and repeat 2 more times so you have a good clean product. Excellent post, we'll definately look into this in the future, sounds quite interesting. The hexane was much brighter, but when we purged, it came out pretty black. Protocol: Winterize the RSO oil in ethanol and filter out waxes, then distill off the ethanol. I just cannot manage to get it to become a shatter consistency. I suggest if you try to read up on it first. Thank you so much! Temperature - The temperature of the cycle wash depends on the validated pre-programmed cycle and cleaning chemistries being used. Dissolve the entire batch in just enough rubbing alcohol to make it dissolve. Method #2, rotovap, or any other way to reclaim. The water layer underneath was clear. Then I use either a battery power hot iron for wood burning craft, or a light to puddle the goop with heat so it is completely liquid and bubbling. An eyelash or two, inevitably some hair, and always some dust. (/d-gold-author-of-cannabis-alchemy-1971-shares-cannabis-extraction-history-unfolding/) Comments.

I saw that middle layer getting thinner and thinner and harder to see each time, as I felt like I got more out of it. Just keep adding solvent until you can pull it all through without a column in place. So am I missing it or did you not publish something using pictures of his samples? the first trip through the flame it is quite a light show. This is our main concern. . Growing cannabis is a fun and exciting hobby unless your plants produce less flower than you had hoped. Acetone is hands down the solvent of choice for cleaning extract and the residue it leaves in a boiling flask. at a certain point the polarity will become just right for the cannabinoids to pass through the column. The best way to remove the grease is to wash the precipitate well with pet.ether 40/60 or 60/80. CHILDREN IN INDIA ARE GOING WITHOUT!!!

A rice grain size vaped into my Vapir 1 bag fills the bag twice with a dense foggy cool sweet orgasmic vapor. Step 3: have 6-8 filters , jars &funnels ready, i usually have my alcohol oil mix into 2 liters glass mason jars so i can filter as quick as possible so the waxes, chlorophyll etc..does not dissolve back into the alcohol ( which will happen if the alcohol starts to reach room temperature). look in the CBD threads instead. No fear. After it has separated, bleed off the water and emulsion layer. First off ,freeze your alcohol and plant material separately for a good 24 hours ( never wash at room temperature! The THCA content of these crystals can be as high as 99 percent but can fluctuate depending on residual solvent and terpene content. Set aside and come back in 1/2 hour. One thing I notice is it takes quite a long time for bubbling to become visible. Let me go through everything in more detail. A couple bucks at the Chevron mart. Another vape hit. And then repeat steps 1-7? It sputters and pops and crackles something fierce. Sorry, we don't have an account for that email. mandurah news body found Login. I cover them with rubbing alcohol. Hazards What is this information? 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. Oops! American Pot Story: Oaksterdam highlights the journey of cannabis advocates and concerned citizens in California during a time of significant change. I wanted to know the best way to clean the 8 oz of green wax. #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. I have not included the full details as I have been asked not to discuss this in this site for safety reasons. We are outside the States. Pour off mix into seperatory funnel. 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. 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. This HTSFE is comprised of high potency THCA crystals with a layer of terpenes. Chemical name :N-Pentane Supplier's details : N-Pentane Product use :Synthetic/Analytical chemistry. They worked well for our purpose, and we cleaned them when they clogged, by alternating a hot aqueous NaOH solution and a HNO3 solution, to break organic bonds. 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. *if you are left with dark chunks in your pure thca seperate these out repeat steps #4+ When left outside for 20min (45-50F) the solution solidified. 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? GW. 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.

Ideas are more than welcome! I use aluminum oxide as the stationary phase and the solvent system I use is water/iso mix. Finally, if you really want to see the separation, obtain a glass tube. Insert a pipette with square tip into the bottom of the test tube (rounded bottom), and remove the liquid, leaving the washed solids behind. . Just using acetone/salt water is unlikely to work, and 2. May do it with an ounce or a pound, advice on both quanties would be great. 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. Orders of magnitude more potent than ground up herb in the unit which the unit is really meant for.

Insoluble in water. Salting alcohol is well known. 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. Further processing of these diamonds can be performed after the purge. 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). everyone recrystallizes their CBD. For iso, it takes (I am told) 15 grams of iso to really cause hurt most sane persons wouldn't want. thank's for the information. I use HPLC greate 99% hexane. Neem oil with azadirachtin has been given to children orally in the Far East for various remedies for a very long time. Remove when brisk bubbling is over. We buy the salt cheap by the bag, using salt intended for water softener use. com https://onlinecannamedshop.com. Hello, you can remove it washing with n-pentane your sample (if is not soluble . This attests to safety. While the black color was gone, slight ashtray undertones could still be tasted, so further refining was necessary with activated charcoal, but we will cover that as a separate subject. Even at lower temperatures, pentane will release many vapors. 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. Close the vessel and very slowly increase the temperature to 25-35oC over the course of 5-30 days. 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). - Do we really need salt in the water? Hello! June 29, 2022. I'm led to understand that salt water is about as polar as you can get and should remove chlorophyll, as well as other polar solvent-soluble materials. Once the solvent is recovered, transfer your solution (cannabinoids/solvent/terpenes) to a pressure-rated crystallization vessel, which can be any vessel that handles pressure and has a pressure gauge, pressure release valve, and a vent valve. It is a sort of thin film chromatography separation and works surprisingly well for seperating the components of an extract. Salting down is a method of fractionalization for this solution. Looking forward to your video! I wring the tea bags and am left with white waxy stuff and other solids. Perfect for separations like this. But it's dark ! Because I didn't want to mess up a separatory funnel with the black foul smelling mess, I poured the solution in a 1 gallon Ziploc bag, to which I added equal amounts of water and hexane.
