FIELD: chemistry.
SUBSTANCE: method of alkyl ester obtainment involves, for instance: mixing of triglyceride-containing oil source with primary alcohol or secondary alcohol in organic solvent to obtain a solution; where each organic solvent molecule includes 4-8 carbon atoms and heteroatom; triglyceride reaction with primary alcohol or secondary alcohol in the presence of lipase immobilised on a carrier, to obtain alkyl ester, where solution does not undergo phase separation in the course of reaction, and glycerin is produced as a by-product; and obtainment of alkyl ester by phase separation in alkyl ester and glycerin after extraction of organic solvent and unreacted primary or secondary alcohol by condensation.
EFFECT: obtainment of mix with high content of high-purity alkyl esters.
