Production method of acrylamide

A method for the continuous preparation of acrylamide from acrylonitrile using a biocatalyst, after introducing the acrylamide to the reactor, and wherein the initiating the continuous reaction by contacting the acrylonitrile biocatalytic method for producing acrylamide I will provide a. Method of manufacturing acrylamide, after the start of the continuous reaction, can be removed acrylamide aqueous solution having a concentration of interest in a short time continuously, excellent low cost and operability.
