APPARATUS FOR PRODUCING ALKOXYPOLYALKYLENE GLYCOL MONO(METH)ACRYLATE AND PRODUCTION PROCESS USING THE APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a process for the production of an alkoxypolyalkylene glycol mono(meth)acrylate applicable as a monomer for a high-performance cement dispersing agent to enable the total condensation of a gaseous distillate before entering into a water separator in the continuous mass production of the ester. SOLUTION: The apparatus for the production of an alkoxypolyalkylene glycol mono(meth)acrylate applicable as a monomer for a cement dispersing agent is characterized in that the ratio of the heat transfer area of a condenser to condense and liquefy the distillate distilled out from a reactor and containing water produced by reaction to the volume of the reactor for the esterification reaction is within the range of 1.0 to 20.0 m-1.
