METHOD OF PRODUCING ALKYL-GLYCERINE ETHERS FROM MARINE FATS Russian patent published in 2011 - IPC C07C43/13 C07C41/16 C07C41/40 C11B11/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of extracting alkyl-glycerine ethers having high biological activity from marine fats. The method involves alkaline hydrolysis of fat, acidification of the mixture, washing the mixture with water, first crystallisation of the mixture in an organic solvent, filtration, drying, second crystallisation of the intermediate product from the organic solvent, filtration and drying. The organic solvent used during first and second crystallisation is hexane or acetone and during the first and second crystallisation, the fat mixture is held in the organic solvent first for 12 hours at room temperature and then for 12-15 hours at 0-4°C, where during the first crystallisation, the ratio of the fat mixture to the organic solvent is equal to 1:10 kg/l, 1:50 kg/l during the second crystallisation, for hexane and 1:10 kg/l for acetone.

EFFECT: invention obtaining end products with high degree of purity and high output using an efficient and cheap method.
