METHOD OF DECOMPOSING BY-PRODUCT OF (METH)ACRYLIC ESTER PRODUCTION

摘要

PROBLEM TO BE SOLVED: To provide a method for controlling production of olefins as by- products in which Michael addition reaction products produced as by-products in a (meth)acrylic ester production process are decomposed and (meth)acrylic acid, a (meth)acrylic ester and an alcohol are recovered. SOLUTION: The method comprises thermally decomposing by-products of the production of a (meth)acrylic ester from an alcohol having a≥3C branched chain, the decomposition being conducted in the absence of any catalyst.
