ABSTRACT:
A process for continuously manufacturing acrylamide by hydrating acrylonitrile in the presence of a free metallic copper catalyst, characterized in that a reactor is employed, which is internally partitioned into a catalyst slurry circulating section and a catalyst precipitating section, and that raw materials and supplementary catalyst are supplied continuously into the reactor and at the same time the clear reaction liquid and a portion of the catalyst are continuously taken out of the reactor so that the properties of the catalyst are maintained constant.
