摘　　要：一类新型负载钯催化剂：〔（N-膦酸亚甲基）亚氨基二乙酸-亚磷酸氢〕锆-钯催化剂由Zr（HPO3）2-x〔O3PCH2N（CH2CO2H）2〕x·H2O与Pd－Cl2在无水乙醇中络合制得。用IR，XPS谱对该催化剂进行了表征，并研究了催化剂的X值，钯含量，＞NCH2CO2H／Pd摩尔比，反应温度，PH值，溶剂和底物对加氢活性的影响。催化剂重复使用8次而无显著失活。Zirconium [(N － phosphomethyl) iminodiacetic acid － phosphite] － palladium,a new type of supported palladium catalyst was prepared by complexing of Zr (HPO3)2－ x [O3PCH2N (CH2CO2H)2]· H2O with PdCl2 in ethanol. The catalysts were characterized by IR, XPS and indicated that N, C = O had taken part in the complexing of palladium(Ⅱ). The hydrogenation of substituted olefines and nitrobenze under atomospheric pressure catalyzed by the title catalyst was studied. Effect of x, Pd%, NCH2CO2H/Pd ratio, reaction temperature, solvents, PH and substrates on the catalyticactivity in hydrogenation was also discussed. The catalyst can be reused eight times without serious loss of activity.
