SYNTHESIS METHOD FOR 2,2'-DIPYRIDINE USING SUPPORTED BIMETAL NANO CATALYST

WIPO Patent Application WO/2017/181514

A1

Disclosed is a method for synthesizing 2,2'-dipyridine using a supported bimetal nano catalyst. The supported bimetal nano catalyst M1-M2@Al2O3 is used as a catalyst to catalyse the direct coupling reaction of pyridine for synthesizing 2,2'-dipyridine. The supported bimetal nano catalyst M1-M2@Al2O3 therein is a catalyst with Al2O3 as a carrier and any two different metals M1 and M2 as active components, wherein M1 and M2 are each independently selected from noble metals Pd, Pt, Ru, Au, Ag and Rh, or non-noble metals Ni, Cu, Fe, Zn and Co. By applying the supported bimetal nano catalyst in the direct coupling production of 2,2'-dipyridine from pyridine, the production efficiency is high, and pollutants which are harmful to the environmentare not produced.
