Abstract
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.
Claims11
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.
