Title:
CATALYST FOR AMINATING POLYETHER POLYOL AND PREPARATION METHOD THEREOF AND METHOD OF PREPARING A POLYETHERAMINE USING CATALYST
Document Type and Number:
WIPO Patent Application WO/2017/079965
Kind Code:
A1
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 roasting 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.
