METHOD OF OBTAINING DOCOSAHEXAENOIC ACID Russian patent published in 2014 - IPC A61K31/20 A61K35/60 C11C1/02

Abstract RU 2537252 C1

FIELD: chemistry.

SUBSTANCE: method of obtaining docosahexaenoic acid includes alkaline hydrolysis of marine fats, processing salts of fatty acids with iodine solution, extraction of iodine-lactones of fatty acids with non-polar organic solvent, removal of free fatty acids which did not react from mixture, opening iodine-lactones of fatty acids with silylating agent, neutralisation of released free iodine with sodium thiosulphate and extraction of free fatty acids with non-polar organic solvent at certain conditions.

EFFECT: method makes it possible to obtain end high-purity product with increased output.
