Catalyst and method for hydrogenation of 4,4′-methylenedianiline |
摘要 |
Disclosed is a catalyst for hydrogenation of 4,4′-methylenedianiline (MDA), including a support, a magnesium-aluminum oxide layer covering the support, and a rhodium-ruthenium active layer loaded on the magnesium-aluminum oxide layer, wherein the rhodium and the ruthenium of the rhodium-ruthenium active layer have a weight ratio of 40:60 to 10:90. The hydrogenation catalyst can be collocated with hydrogen for hydrogenation of the MDA to form bis(para-amino cyclohexyl) methane (PACM), and the PACM contains 0 mol % to 25 mol % of (t,t)-isomer. |
