Abstract
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.
