METHOD FOR PRODUCING (METH)ACRYLATE ESTER

摘要

Disclosed is a method for producing a (meth)acrylate ester wherein a high purity (meth)acrylate ester is obtained with a high yield, with a reduced loss of (meth)acrylic acid anhydride. In the method, (meth)acrylic acid is recovered with a high yield, and the (meth)acrylate ester is purified easily. Specifically disclosed is a method for producing a (meth)acrylate ester which comprises: (1) a step of producing (meth)acrylic acid anhydride by reacting a specific fatty acid anhydride and (meth)acrylic acid, while removing a by-produced fatty acid; (2) a step of obtaining a (meth)acrylate ester by reacting an alcohol and unpurified (meth)acrylic acid anhydride obtained in step (1) preferably at a temperature not less than 90 °C; and (3) a step of recovering (meth)acrylic acid by distillation preferably at a temperature not less than 90 °C. The method may also comprise a step of heating or distilling the reaction liquid obtained in step (2) at a temperature not less than 90 °C.
