METHOD AND APPARATUS FOR PRODUCTION OF DIALKYLAMINOALKYL (METH)ACRYLATE QUATERNARY SALT

摘要

Disclosed is a method for producing a DAM at high productivity and high purity by cooling a reaction solution efficiently to control the increase in temperature in a reactor. Also disclosed is a production apparatus suitable for the method. Specifically disclosed is a method for producing a dialkylaminoalkyl (meth)acrylate quaternary salt by continuously feeding a dialkylaminoalkyl (meth)acrylate, a quaternarizing agent and water to a reactor, while continuously draining a reaction solution from the reactor, wherein a part of the reaction solution is drained from the reactor, is cooled by passing through a heat exchanger, and then is fed into the reactor together with the quaternarizing agent by means of an ejector.
