［（N，N－二膦酸亚甲墓）甘氨酸－磷酸氢］锆－钯催化剂的催化加氢活性

Catalytic Activities of Zirconium (Glycine-N,N-dimethylphosphonate)-palladium in Hydrogenation

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.
