摘要: 磷酸氢锆及有机膦酸锆是一类具有层状结构的材料,引入活性中心或活性基团可以用作催化剂或催化剂载体[1]. 典型的α-磷酸氢锆和有机膦酸锆具有较大的比表面[2]. 我们曾制备了磺化苯膦酸锆[3]、(磷酸氢-二苯基次膦酸)锆-氯化铁复合物[4]和磷酸氢锆固载的季铵盐[5]

Abstract: A new type of supported complex catalysts, zirconium glycine-N,N-dimethylph osphonate palladium was prepared for the first time. The catalytic activity of title catalysts for hydrogenation of several substrates under atmospheric pressure was studied. The catalytic activity is greatly affected by the NCH2CO2H/Pd ratio, catalyst amount, reaction temperature, substrates and solvents. At 40℃ and under atmospheric pressure, the hydrogenation activity of the catalysts for various substituted olefins and nitrobenzene is very high and with high selectivity. The catalyst can be reused.

Key words: zirconium glycine-N, N-dimethylphosphonate, palladium catalyst, catalytic hydrogenation, catalytic activity
