Abstract
The invention is to provide a process for effectively removing impurities contained in an amide compound-containing solution by making an amide compound-containing solution, particularly an amide compound-containing solution produced by a hydration reaction of a nitrile compound by using a microorganism fungus body containing nitrile hydratase or a processed product of the microorganism fungus body, in contact with activated carbon under acidic conditions.
