Abstract
Official abstract text for this publication.
A method for producing acrylamide from acrylonitrile by a biocatalyst method, wherein both evaporation of acrylonitrile into a gas phase and damaging of a catalyst by stirring are prevented, is provided. In the present invention, the production of acrylamide from acrylonitrile by the biocatalyst method comprises feeding acrylonitrile into an aqueous medium comprising a microbial catalyst.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing acrylamide in an aqueous medium by feeding acrylonitrile to said aqueous medium supplemented with a microbial catalyst(s) while stirring said aqueous medium, comprising: placing, in said aqueous medium, a feed opening of an acrylonitrile feed tube that feeds acrylonitrile to said aqueous medium to prevent an evaporation of acrylonitrile into gas phase and to enhance a reaction yield of acrylamide from acrylonitrile, wherein the feed op…
