摘　　要：合成了四元杂多配合物 (NH4 ) 15[Y(PMo9V2 O3 9) 2 ]·5H2 O ,将其用于苯酚过氧化氢羟化制苯二酚 ,获得了选择性单一、转化率较高的催化效果 ,苯酚转化率可达 41.2 3% ,对苯二酚产率可达 40 .11% ,产物中未检出邻苯二酚 .探讨了温度、溶剂、物料比。The synthesis of ytterbium molybdovanadophosphate heteropoly complex and the application of this heteropoly complex in catalyzing phenol hydroxylation were reported. The results of onefold selectivity and high conversation were got: the conversation of phenol was 41.23%, the yield of hydroquiaone was 40.11% and the catechol hadn't been detected. The effect of temperature, solvent, medium pH value and the ratio of catalyst and phenol on the catalytic activity was also discussed.
