I had to dry the acetone completely and it was nasty, I had to do a mini stb on the goo with lye and naptha to get it clean enough. Solvent extraction is the most widely used method. All of these solutions help to modify the (organic) compound and make it more water-soluble and therefore remove it from the organic layer. . Bench scale experimental results are reported on removing 2,4 dinitrotoluene (DNT) from sand and clay samples via packed bed or stirred tank methods of extraction. One processing advancement under investigation is the development of nonconventional solvent extraction (SX) stripping techniques such as hydrogen, hydrolytic, and precipitation stripping. The extract of ethyl acetate and acetone is equivalent, but when purified by PSA, ethyl acetate provides a better purification effect than acetone. Keep adding acetone to the test tube until all of the extract has been dissolved in acetone. Answer (1 of 2): It is a way to purify alkaloids relatively easily.

Attempts have been done to enhance lipid extraction yield by adding more solvent to wash the post-extracted biomass, or washing the post-extracted biomass with the extracted mixture (solvent and lipids mixture), but without any improvement [].Our results also show that in the control group, most of the extraction occurred in the first extraction step, with the second extraction yield only . Water seems to be a perfect medium for this purpouse. Though pioneered by R134a, this method is efficient with carbon dioxide extraction to eliminate the need for further procedures; R134a extracts terpenes and live resins in10-15 minutes, while ethanol separates cannabinoids in about 30-60 minutes.
