Kind Code:
A3
Abstract:
The present invention provides technology for improving the selectivity of a (meth)acrylic acid ester. The present invention relates to a (meth)acrylic acid ester production method including: reacting (meth)acrylic acid and a secondary alcohol within a reactor and in the presence of an acid-type esterification catalyst and a polymerization inhibitor; and supplying an alkene-containing material obtained during production of the (meth)acrylic acid ester to the reactor such that the ratio of alkene concentration to secondary alcohol concentration within the reactor is 0.001 or more.
