Process for producing glycidyl (meth)acrylate

摘要

Provided is glycidyl(meth)acrylate which is reduced in the content of impurities including chlorine. This process comprises reacting epichlorohydrin with an alkali metal (meth)acrylate in the presence of a catalyst to produce glycidyl(meth)acrylate, the process including a step in which the reaction is conducted while making a Bronsted acid present in the reaction system in an amount of 0.0001-0.08 mol per mol of the alkali metal (meth)acrylate.

1. A process, comprising:
reacting epichlorohydrin with an alkali metal salt of (meth)acrylic acid in the presence of a catalyst, thereby producing glycidyl (meth)acrylate, wherein reacting the epichlorohydrin with the alkali metal salt of (meth)acrylic acid is in the presence of a Broensted acid in a reaction system in an amount of 0.0001 mol to 0.08 mol per mol of the alkali metal salt of (meth)acrylic acid, wherein a total content of chloropropenyl (meth)acrylate and 1,3-dichloro-2-propanol in a reaction solution is 2770 ppm or less, wherein the catalyst is a quaternary ammonium salt and/or an ion exchange resin comprising a quaternary ammonium salt.
