    摘要： A process for the hydrogenation of aniline to produce cyclohexyl amine is disclosed wherein the reaction is carried out in a distillation column reactor at a hydrogen partial pressure in the range of 0.1 psia to less than 100 psia. The catalyst is prepared in the form of a catalytic distillation structure. Within the distillation reaction zone there is an internal reflux and liquid from an external reflux which cool the rising vaporous aniline condensing a portion within the bed.

    摘要： This invention relates to an improved hydrogenation process wherein methylenedianiline is reduced to form bis(para-aminocyclohexyl)methane (PACM). The process contemplates contacting methylenedianiline and hydrogen in the presence of a two component metal catalyst comprising rhodium and ruthenium under mild hydrogenation conditions. Use of the mixed metal catalyst system allows one to obtain a preselected isomer ratio having from about 5-40% by weight, typically 14`28% by weight of the trans,trans- configurational isomer.
