Abstract:
The present invention relates to a catalyst for aminating a polyether polyol and preparation method thereof and a method of preparing a polyetheramine using the catalyst. The catalyst has active components and a carrier. The active components are Ni, Cu, and Pd. The method of preparing the catalyst comprises the following steps: using a metal solution or a metal melt impregnated carrier, obtaining a catalyst precursor; and drying and calcinating the obtained catalyst precursor, so as to obtain a catalyst. By introducing the active component Pd in the catalyst, the present invention clearly improves selectivity of an amination catalyst with respect to a preaminated product, and increases raw material conversion rate.

Claim (Index 15):
The method for preparing polyetheramines by aminating a polyether polyol according to  claim 14 , wherein the polyether polyol is a polyol comprising EO and/or PO backbone(s) with a molecular weight of 100-7000, preferably 106-5000, more preferably 200-500.
