Production of aliphatic primary or secondary amines.

摘要

Prepn. of aliphatic prim. amine comprises reacting a 8-24C aliphatic nitrile with hydrogen at 150-250 deg.C and a hydrogen pressure of 1-50 atm. in the presence of a hydrogenation catalyst and either an alkali metal hydroxide or ammonia. The catalyst contains (a) Cu, (e) a gp.VIII Pt metal and/or (f) a IV period transition metal (not Cu) in a wt. ratio (a/e) of 1/0.0001 to 1/0.1 and (a/f) of 99/1 to 10/90. The catalyst can also contain (c) an alkali or alkali earth metal in a wt. ratio (a/c) of 1/1 to 1/0.01 and (d) at least one metal selected from Al, Mo and W in a wt. ratio (a/d) of 1/1 to 1/0.1.
