摘要
一类新型负载钯催化剂:[(N,N-二膦酸亚甲基)甘氨酸-磷酸氢]锆-钯催化剂由Zr(HPO4)2-x[(O3PCH2)2NCH2CO2H]x·H2O与PdCl2在甲醇中络合和水台胼还原制得.研究了催化剂在常压下对取代烯烃和硝基苯的加氢反应,催化剂的x值、Pd%含量,>NCH2CO2H/Pd比值、反应温度、溶剂和底物对催化加氢活性的影响也进行了研究.催化剂可重复使用8次而无显著失活.[(N,N-二膦酸亚甲基)甘氨酸-磷酸氢]锆;氯化钯;负载;
Zirconium(Glycine-N,N-dimethylphosphonate-phosphate-palladium,A new type of suppportedpalladium catalyst was prepared for the first time by complexing of Zr(HPO4)2-x[(O3 PCH2)2 NCH2 CO2H]x.H2O with PdCl2 in methanol and being reduced with hydrazine hydrate.The hydrogenation of substituted olefines and nitrobenzene under atmospheric pressure catalyzed by thecatalyst was studied. The infuence of x,Pd%,NCH2CO2H/Pd ratio, reaction temperature,solventsand substrates on the cataytic activitieS in hydrogenation was also discussed.The catalyst can be reused eight times without serious loss of activity.
