Process for producing acrylamide using a microbial catalyst having been washed with aqueous acrylic acid solution

摘要

Provided is a process for producing acrylamide with good storage stability and improved acrylamide polymer physical properties using a microbial catalyst. A microbial catalyst having catalytic activity to convert from acrylonitrile to acrylamide is washed with an aqueous acrylic acid solution, and then the washed microbial catalyst is used for the conversion reaction, so that the production of the above acrylamide is achieved.
