US 10,087,159 B2 · Method for producing 3-chloro-2-hydroxypropyl (meth)acrylate and method for producing glycidyl (meth)acrylate

Abstract

To reduce formation of side products and to enhance a selectivity rate in a method for producing 3-chloro-2-hydroxypropyl (meth)acrylate and in a method for producing glycidyl (meth)acrylate. The present invention is characterized by a method for producing 3-chloro-2-hydroxypropyl (meth)acrylate through a reaction of (meth)acrylic acid and epichlorohydrin; more specifically, the reaction is carried out by using 0.5 to 2 mol of epichlorohydrin relative to 1 mol of (meth)acrylic acid, and by adding epichlorohydrin to (meth)acrylic acid in the presence of a catalyst. Also, the present invention is characterized by a method for producing glycidyl (meth)acrylate through a reaction of 3-chloro-2-hydroxypropyl (meth)acrylate and a basic carbonate compound in a polar solvent.

Claims7

Dependent claims

A method for producing glycidyl (meth)acrylate, comprising:

(1) a step of dropping epichlorohydrin into (meth)acrylic acid in the presence of a catalyst to provide 3-chloro-2-hydroxypropyl (meth)acrylate, where 0.5 to 2 mol of the epichlorohydrin is reacted per 1 mol of the (meth)acrylic acid;
and
(2) a step for producing glycidyl (meth)acrylate by reacting the 3-chloro-2-hydroxypropyl (meth)acrylate with a basic carbonate compound in a polar solvent.

Dependencies are inferred from the claim text.
