Abstract
There is herein disclosed a process for preparing a lactamide by hydrating lactonitrile in the presence of a catalyst mainly comprising a manganese oxide, and a nitrogen-containing compound such as ammonia or diethylamine. According to this process, the lactamide can be obtained from lactonitrile in a high yield, while the high activity of the catalyst is maintained for a long period of time.
