Title: Method for extracting phytosterols from tall oil pitch
Inventor: CHERNOV ILIA NIKOLAEVICH
IPC: C07J9/00
Filed: 2018-05-08
Granted: 2020-02-11
Abstract: The invention relates to the wood chemical industry and concerns a method for extracting phytosterols from tall oil pitch. The present method of extracting phytosterols from tall oil pitch involves saponifying tall oil pitch using an alkali in a polyatomic alcohol, extracting unsaponified matter from the alkali-alcohol solution using a hydrocarbon solvent, subsequently removing the solvent by distillation, and concentrating the phytosterols, wherein a mixture of paraffin hydrocarbons is used as said hydrocarbon solvent, and, following extraction from the extraction solution, betulin is isolated by crystallization and the phytosterols are then concentrated by means of rectification. This method makes it possible to increase the rate of extraction of phytosterols from saponified tall oil pitch to up to 95%, and allows an end product to be produced that has a phytosterol content of at least 65% with unwanted betulin impurities at no more than 0.3%.
