ABSTRACT:
The present invention relates to a process for producing an aliphatic nitrile, including the step of reacting at least one compound selected from the group consisting of an aliphatic monocarboxylic acid, an aliphatic dicarboxylic acid and alkyl esters of these acids containing an alkyl group having 1 to 5 carbon atoms, with ammonia in the presence of a compound of at least one metal selected from the group consisting of zinc, cobalt, titanium and aluminum, and a sulfonic acid compound! and a process for producing an aliphatic amine, including the step of subjecting the aliphatic nitrile produced by the above process to hydrogenation reaction in the presence of a hydrogenation catalyst. There are provided an industrially advantageous process for producing an aliphatic nitrile with a high reactivity; and a process for producing an aliphatic amine using the aliphatic nitrile as a raw material.
