Abstract

PURPOSE: To obtain acrylamide in high purity as a raw material for preparing a high-molecular weight polymer especially useful as a coagulant, by hydrating acrylonitrile having not more than a specific ratio of impurity acetone content in the presence of a copper type catalyst.
CONSTITUTION: Acrylonitrile containing ≤3ppm, preferably ≤1ppm acetone is reacted with water in the presence of a copper type catalyst in a liquid phase to give acrylamide. For example distillation operation, extraction with water, etc. may be cited as a method to reduce the content of acetone in acrylonitrile. The prepared acrylamide is high quality, and useful as a raw material for preparing a high- molecular weight acrylamide type polymer having a molecular weight ≥10,000,000, which is especially used as a coagulant, etc.
