Abstract
Amide compounds are efficiently prepared directly from nitriles, amines and water, using a reaction catalyst. The invention also can applied to the manufacture of polyamides, thereby realizing a simplified and rationalized process for polyamide synthesis. The catalyst employable is at least one metallic compound selected from the group consisting of Ru- Rh-, Zn-, Ni-, Mo-, Cu-, Co-, Ti-, Cr-, Zr-, Os-, Rd-, Se-, Fe-, Pb-, Hg-, V-, Cd-, Ir- and Pt-compounds.
