PROCESS FOR PREPARING AMINES BY CATALYTIC HYDROGENATION OF NITRILES

摘要

The present invention relates to a process for preparing amines by the catalytic hydrogenation of nitrites in the presence of a nickel-containing support catalyst. The support catalyst contains Mg and Ni in coprecipitated form, Mg and Ni in a molar ratio of (0.0075 to 0.075):1 and 17 to 60 g of a water-insoluble support per mole of nickel. 65 to 97% of the BET total surface area of the support catalyst is formed by pores having a radius r p ~ 2.5 nm.
