METHOD OF PRODUCING ESTERS Russian patent published in 2012 - IPC C07C67/02 C07C69/03 C07C69/22 C07C69/02

Abstract RU 2453530 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing esters of (C₁₅-C₂₂) fatty acids and (C₁-C₅) aliphatic alcohols, used as viscosity regulators for polyvinyl chloride compositions and industrial rubber articles. The method is characterised by that said compounds are obtained through re-esterification of a mixture of glycerine esters of C₁₅-C₂₂ fatty acids contained in renewable plant material with C₁-C₅ alcohols in molar ratio of oil to alcohol equal to 1:5, on alkaline catalysts, at temperature limited by the boiling point of alcohol, separating glycerine and then vacuum distillation, with output 95-98% of theoretical output with 95% oil conversion in 3 hours.

EFFECT: improved method.
