摘要： A process for the preparation of 1,3 or 1,4-bis (aminomethyl)cyclohexane by hydrogenating a solvent solution of iso- or terephthalonitrile at a temperature between about 50.degree. and about 150.degree. C., at a pressure of between about 500 and about 1500 psig., and in the presence of a supported rhodium catalyst.

摘要： In the process of hydrogenating aliphatic nitriles to primary amines whereby the nitrile is hydrogenated in a solvent system containing added ammonia using a cobalt or ruthenium catalyst, the improvement of employing an ether as solvent and carrying out the hydrogenation in the presence of water in an amount of from about 5% to about 15% by volume of the ether solvent whereby the rate of reaction is increased, and selectivity to primary amine products is increased.

摘要： A process for the hydrogenation of aromatic dinitriles to the corresponding cycloaliphatic aminomethyl compounds by(1) hydrogenating the nitrile in an ether solvent containing water and ammonia using nickel or cobalt as catalyst,(2) removing by-products from the aromatic diamine thus produced,(3) subjecting the aromatic diamine to hydrogenation with a ruthenium catalyst in an aqueous solvent system devoid of ammonia and(4) isolating the cycloaliphatic diamine product.
