== Synthesis == Dicyclohexylamine, as a mixture with cyclohexylamine, is prepared by the catalytic hydrogenation of aniline (phenylamine), with a catalyst of ruthenium and/or palladium. This method produces mainly cyclohexylamine with little dicyclohexylamine. Better results have been reported when the catalyst is applied to a support of niobic acid and/or tantalic acid. It is also obtained by reductive amination of cyclohexanone with ammonia or cyclohexylamine.
