This invention provides a process for forming secondary diamines. The process comprises bringing together i) at least one aliphatic cyclic ketone, ii) at least one aliphatic primary diamine, iii) hydrogen, and iv) a hydrogenation catalyst. The aliphatic primary diamine is isophoronediamine or an aliphatic primary α,ω-diamine, and the hydrogenation catalyst is selected from platinum on carbon, palladium on carbon, sulfided platinum on carbon, sulfided palladium on carbon, and a mixture of any two of the foregoing. The process is conducted at a temperature in the range of about 200C to about 750C and at a hydrogen pressure in the range of about 1 to about 95 pounds per square inch gauge, such that a secondary diamine is formed.
