| titleOfInvention | Preparation of secondary diamines |
| abstract | This invention provides a process for forming secondary diamines. The process comprises bringing together (a) at least one aliphatic hydrocarbyl ketone or aldehyde in which the carbon atom(s) alpha to the carbonyl group are primary or secondary and the hydrocarbyl portion of the ketone or aldehyde is linear or branched; (b) at least one aliphatic primary diamine which is an aliphatic pirmary α, ω -diamine, (c) hydrogen; and (d) a hydrogenation catalyst 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 20EC to about 76EC and at a hydrogen pressure in the range of about 1 to about 85 pounds per square inch gauge, such that a secondary diamine is formed. |
