摘要:
Provided is a catalyst for amide compound hydrogenation characterized in that rhodium and molybdenum are supported on hydroxyapatite, the catalyst for amide compound hydrogenation providing a catalyst that can promote a reduction reaction that converts an amide compound into an amine compound, can be used under moderate conditions, and has durability that allows repeated use thereof while retaining high activity. Also provided is a method for producing an amine compound, the method being characterized by including bringing an amide compound into contact with the catalyst for amide compound hydrogenation to cause hydrogenation, thereby producing an amine compound.

The present invention provides a method for preparing 3-aminomethyl-3,5,5-trimethyl cyclohexylamine. The method comprises: a) reacting 3-cyano-3,5,5-trimethyl cyclohexanone with excess primary amine as well as removing the water generated from the reaction, so that IPN is substantially converted into imine compounds; b) in the presence of an ammonolysis catalyst, mixing the product of step a) with liquid ammonia, making the imine compound perform ammonolysis reaction to generate 3-cyano-3,5,5-trimethyl cyclohexylimine and the primary amine; and c) in the presence of hydrogen and a hydrogenation catalyst, hydrogenating 3-cyano-3,5,5-trimethyl cyclohexylimine obtained in step b) to obtain 3-aminomethyl-3,5,5-trimethyl cyclohexylamine. The method of the present invention avoids the generation of 3,5,5-trimethyl cyclohexanol and 3-aminomethyl-3,5,5-trimethyl cyclohexanol as the major by-products in the prior art, thereby improving the yield of 3-aminomethyl-3,5,5-trimethyl cyclohexylamine.
