摘要： Disclosed is a method for preparing diamino-dicyclohexyl methane (H 12 MDA) by hydrogenation of diamino-diphenyl methane (MDA). In the process, 4,4'-MDA used as the starting material is firstly hydrogenated to prepare 4,4'-H 12 MDA. When the activity of the catalyst is reduced, the feed is switched from 4,4'-MDA to the mixture of 2,4'-MDA and 4,4'-MDA, and then when the conversion is stabilized, the feed is switched to 4,4'-MDA again. The deactivated catalyst is activated on line by switching the feed to the mixture of 2,4'-MDA and 4,4'-MDA. 4,4'-H 12 MDA having the trans-trans isomer content of 16~24wt% is produced, and the mixture of 2,4'-H 12 MDA and 4,4'-H 12 MDA is also produced, wherein the content of 2,4'-H 12 MDA in the mixture is 4~15 wt%.

摘要： A supported catalyst used for synthesizing a polyether amine, and a manufacturing method of the catalyst. The catalyst comprises: a porous oxide as a support; Ni, Cu, Pd, and Rh as active components; and one or more of any of Zr, Cr, Mo, Fe, Zn, Sn, Bi, Ce, La, Hf, Sr, Sb, Mg, Be, Re, Ta, Ti, Sc, Ge and related metals as an auxiliary agent. The catalyst can be used in an amination reaction for a large molecular weight polyether polyol, and is particularly active and selective for an amination reaction of a low molecular weight polyether polyol. The catalyst has a simple and economic manufacturing technique and good potential for future applications.
