Abstract

The invention is a process for continuously producing an amide compound by reacting a microorganism fungus body containing nitrile hydratase or a processed product of the microorganism fungus body with a nitrile compound in an aqueous medium, characterized in that after contacting said fungus body or said processed product of said fungus body with said nitrile compound in said aqueous medium, a reaction solution thus obtained is further subjected to reaction under conditions having a plug flow region, and according to the invention, an amide compound aqueous solution of a high concentration a high purity can be easily obtained in an extremely high conversion rate of a nitrile compound without a condensation process.
