Process for the continuous production of acrylamide or methacrylamide using microorganisms |
摘要 |
A process for the continuous production of acrylamide or methacrylamide from acrylonitrile or methacrylonitrile by use of a microorganism capable of promoting the hydration of acrylonitrile or methacrylonitrile into the corresponding amide. Said process comprising immobilizing the microorganism or enzyme extracted therefrom, continuously bringing the acrylonitrile or methacrylonitrile into contact with the immobilized microorganism or enzyme in at least one reactor containing an aqueous medium at a pH pf 6 to 10 to cause the hydration reaction, and recycling a part of the reacted solution to dilute the unreacted acrylonitrile or methacrylonitrile and water therewith.
