Method of producing an acylated derivative of an epoxy fatty acid ester or epoxy natural oil

摘要

An improved method of producing an acylated derivative of an epoxy fatty acid ester or epoxy natural oil, by reacting the epoxy fatty acid ester or epoxy natural oil with a vinyl aliphatic monocarboxylic acid in contact with a catalyst, a polymerization inhibitor and gaseous oxygen, the improvement of adding the monocarboxylic acid, or the acylation catalyst or a mixture of the monocarboxylic acid and the acylation catalyst, to a reaction mixture at an elevated temperature and maintaining an elevated temperature until completion of the reaction.
