oct 21, 2016 something ive always been curious about. thc is soluble in fats and oils. thc is soluble in alcohol, but thc is not soluble in water. what doesnt make sense to me about this is the fact that the main functional group in alcohol is the same as the main bonding form in waterjul 14, 2013 judging by the links you assume that the water dissolves or weakens the attachment of grains of chlorophyll within the chloroplast? unfortunately, these articles are not readily available to my understanding. My familiarity with the anatomy of the cell is limited only by was interested
sep 27, 2016 you seem like a smart guy, good write-up. can suggest a couple refinements though. think youll find that 50% ethanol is more selective than 100%, leaving behind the chlorophyll and some other stuff thats only soluble in high concentration ethanol while still dissolving most of the cannabinoids.chlorophyll is highly soluble in alcohol and slightly soluble in butane. for further discussion of that subject, please see: processes that use a polar solvent and reflux or soxhlet to maximize extraction, also maximize and concentrate chlorophyll
chlorophyll chlorophyll xanthophyll, carotene. the more non-polar a pigment, the more soluble it is in nonpolar solvent. which pigments move faster up the paper. spinach and acetone tube, carrot and acetone tube, and in acetone blank tube. photosynthesis equation.aug 01, 2013 is to be separated and discarded are ether and petroleum ether the same? no! petroleum ether is a petroleum product. real ether is. more commonly known as diethyl ether or ethyl ether. its chemical. formula is -o-, and it is not a petroleum product.
jan 15, 2013 the acetoneiso also doesnt seem to evaporate as well. As noted in the post above you want the driest acetone one can get to ensure that no unwanted water soluble components end up in the oil the oil obtained is different from butane hash oil, being thicker with a different colour and less pure. It can be difficult to smoke, the best way in my oct 02, 2005 acetone, and alcohols extract thc well. acetone does get some other unneeded stuff too, so ethanol would be reccomended. also, soaking your marijuana in a mild high ph results in decarboxalation of the thc-cooh, which remains inactive, to thc; other cannabinoids seem to undego this process too.
feb 06, 2020 the orange colored band, made of the pigment called carotenoids. is the most soluble in alcohol, so it traveled the farthest. the yellow xanthophylls are the next most soluble, followed by the blue-green chlorophyll the least soluble pigment is the yellow green chlorophyllether will dissolve cannabinoids but leave behind chlorophyll and sugars. alcohols and acetone will dissolve cannabinoids, hence thc is soluble in all solvents except water it is more soluble in polar solvents, but is is better to use more of a non-polar solvent and get pure thc than to use a smaller amount of a more polar solvent and co
the solubility parameters of the solvents and cannabinoids are widespread. ethanol, isopropyl alcohol, acetone, and 710 spirits have similar parameters, as is the case with chlorophyll and plant waxes. there is also a large grouping of terpenes that have parameters that are close together. this indicates that some solvents will be more suitable nov 12, 2012 have done acetone it pulled all the chlorophyll out of the plant matter it was the worst oil have ever smoked thick with plant matter yuck only used it because before was well informed and quite stupid used to use alternative forms of thc such as jwh 018 and a neither or any for that matter do suggest to anyone for any reason
make the solvent system more polar if you want a larger Rf or make it less polar if you want to decrease the rf. also, if there is streaking of your compound on the plate -basically you see large streaks instead of sharp circles your sample is probably too concentrated. try diluting your sample and running the mar 11, 2010 read a method of thc extracting using acetone as a solvent and then distilling it off leaving a thc goo that could be combined with powder to form a hash oil so can only assume ethanol addition is very similar, especially if the acetone thc rxn is completed by heat break down of the ketone to a reactive molecule that mixes with the thc.

jun 29, 2015 My own knowledge of cannabis extraction is limited mostly to quick solvent wash techniques. So far have found that butane, isopropyl alcohol and acetone have the potential to enable extraction of hashish and cannabis oil. Of the three, butane can be most effective, producing a purer and more potent product .evaporation times of small amounts appear to be the lowest nov 01, 2018 190 proof ethanol is actually preferred to pure ethanol. while also being cheaper, 95% ethanol has water making it ever so slightly more polar. this is beneficial for winterization because the cannabinoids remain soluble even at cold temperatures whereas the waxes are insoluble and crash out of solution. get as close to -80 as possible.
mar 03, 2020 dont be dismayed when you see such a small amount of material. It should contain at least 70% thc and a little goes a very long way. final thoughts on using rubbing alcohol to extract thc from weed. the answer to the title question is yes, but with a fair number of caveats.dec 05, 2010 chlorophyll is not soluble in water. very little green color is found in the water in which green vegetables have been cooked. pure isolated chlorophyll is soluble in acetone, ether and benzene. In extracting the pigment from thoroughly dry leaves it is necessary to add about per cent of water to the acetone or other solvent.
re: cannibinol d-6-thc d-6-thc acetatete synth bookmark acetone isnt a very selective solvent, low molecular weight hydrocarbons such as heptane, hexane, pentane or butane work better. petroleum ether aka naptha is a mixture of these hydrocarbons, thats why its the preferred solvent. obituary No dec 26, 2018 preheating of cannabis samples has been recommended as a way to potentiate the final extract, i.e. to decarboxylate the acidic cannabinoids naturally present in cannabis plant material, such as thca and cbda, and turn them into their more potent counterparts such as thc and cbd 18,19.and eudesma-3,7-diene remained.
nov 04, 2013 thus, polar solvents, especially water, travel more slowly and allow less resolution between pigments. acetone provides a great middle ground for this process because it is amphipathic.for more information about the different types of plant pigments, provide this resource for students to review: photosynthetic pigments (chlorophyll a is a bright green to blue-green. chlorophyll is a yellow- the most soluble pigment in the etheracetone solvent traveled the farthest, and that is the carotene.
oct 10, 2010 the pigment is then much more soluble, in ether, etc even when the leaves are subsequently dried. It is supposed that the chlorophyll has diffused out from the plastids, and is in true solution in the accompanying waxy substances which have become liquid owing to butanes relative non-polarity means it doesnt extract water-soluble compounds like chlorophyll, made up principally of terpenes but also containing the full spectrum of secondary cannabinoids and flavonoids for a more complete effect. hcfse will have a thc-a content of around 90% and will look more like diamonds coated in sauce,
chlorophyll-a will produce a bright green to blue green color cholorphyll-b will produce a color which is yellow green to olive green. yellow to yellow orange or possibly red will be produced by carotenoids. pale yellow is produced by xanthophylls. all of these pigments are located in the chloroplasts. these pigments are not water soluble.pigment is likely to be chlorophyll, since it is more polar than carotenes but less polar than xanthophylls. you can observe the characteristic green colour from chlorophyll on the chromatogram. figure chromatograms and corresponding Rf values for two leaf samples using a mobile phase of hexane, acetone and
If youre dissolving resin alongside waxes, lipids, chlorophyll and other secondary compounds then the solubility drops to around half, so youd get gml. other information contradicts this, giving a solubility of gml for thc and more than twice that, gml for cbd, although its unclear at what temperature the extractions were carried non-polar solvents such as benzene, chloroform and petroleum ether will not extract the water-soluble constituents of marijuana or hashish, and will yield a more potent oil as a result. polar solvents such as alcohol will extract undesirable water soluble substances such as chlorophylls and sugars.
apr 13, 2010 the simplest method of column chromatography is performed with ethanol and ether extracts of hemp on alumina, yielding two major fractions: chlorophyll, cbd, and cbn, and thc. second, more difficult method is performed on florisil with the solvent system hexane:2% methanol.
