Abstract
A method for producing an amide compound from a nitrile compound in an aqueous medium in the presence of a catalyst having a nitrile hydratase activity wherein the concentration of benzene in the aqueous medium is 4.0 ppm or less and a method for producing an amide-based polymer excellent in quality from the amide compound. Also provided are a method for more efficiently producing an acrylamide with higher quality by a microbial catalyst containing a nitrile hydratase and the like and a method for producing an acrylamide-based polymer, which is excellent in hue, has a good balance between water solubility and high molecular weight and is excellent in quality.
