  • Amide compound production catalyst, and process for production of amide compound
    Patent number: 8603939
    Abstract: The present provides a high-efficiency amide compound production catalyst to be used in producing an amide compound through hydration of a nitrile compound and a production method using it. The amide compound production catalyst is for producing an amide compound through reaction of a nitrile compound and water, and comprises a manganese oxide catalyst containing bismuth and further containing yttrium or vanadium. The method for producing an amide compound comprises reacting a nitrile compound and water in a liquid phase in the presence of the amide compound production catalyst.
