METHOD FOR PRODUCING SORBITAN AND FATTY ACID ESTERS Russian patent published in 2017 - IPC C07C69/33 C07D307/20 B01F17/34

Abstract RU 2636743 C1

FIELD: chemistry.

SUBSTANCE: in the proposed method for producing fatty acid and sorbitan esters, vegetable oils interact directly with sorbitol in the presence of a catalytic system consisting of hydroxy acid and sodium hydroxide at the molar ratio of 0.8:1.2-1:2 and at the concentration of the catalyst system of 2-4 wt % in terms of sorbitol.

EFFECT: efficient method for producing sorbitan and fatty acid esters.
