摘要
采用重结果法制备了催化剂Na12[WZn3(H2O)2(ZnW9O34)2](CatZn)。以1,2-丙二醇(1)催化选择性氧化制备羟基丙酮(2)为探针反应考察了CatZn的催化性能。在最佳反应条件[1 50 mmol,n(CatZn)∶n(1)=0.06,n(H2O)∶n(1)=1.4,n(H2SO4)∶n(1)=0.15,于70℃反应1.5 h]下,收率43.85%,选择性68.87%。
Na12 [WZn3(H2O) 2 (ZnW9O34)2] catalyst (CatZn) was prepared by recrystallization method.Catalytic activity of CatZn were investigated by selective oxidation of 1,2-propandiol (1) to hydroxyacetone(2).Yield was 43.85% and selectivity was 68.87% under the optimum reaction cnditions[1 50 mtmol,n(CatZn) ∶ n(1) =0.06,n(H2O) ∶ n(1) =1.4,n(H2SO4) ∶ n(1) =0.15,at 70 ℃ for 1.5 h].
