Abstract
The application relates to the technical field of organic synthesis, in particular to a catalyst for catalytic synthesis of N,N,N',N'-tetramethyl ethylenediamine and a preparation method and application thereof. The copper-nickel-cerium-zirconium catalyst is composed of CuO-NiO-CeO2-ZrO2; wherein the molar ratio of CuO, NiO, CeO2 and ZrO2 is (60-65):(5-25):(10-25):(1-10). The copper-nickel-cerium-zirconium catalyst provided by the application can efficiently catalyze the reaction of dimethylamine and ethylene glycol to prepare N,N,N',N'-tetramethyl ethylenediamine, the conversion rate of ethylene glycol can reach 99%, and the selectivity of N,N,N',N'-tetramethyl ethylenediamine can reach 90%.
