中文摘要：

以30％H2O2溶液为氧化剂，以六配位水和三配位水的铋钨杂多酸四丁基铵盐（[（C4H9）4N]10[（M^Ⅱ（H2O）3）2（WO2）2（BiW9O33）2]和[（C4H9）4N]12[（M^Ⅱ（H2O））3（BiW9O33）2]（M=Ni，Mn，Co））为催化剂，催化了环己烯环氧化反应，探索了杂多酸催化剂中配位水的数量对催化剂性能的影响．结果表明：HiO2（30％）与环己烯的物质的量比为3：1，反应温度为80℃，反应时间为6h，六配位水的铋钨杂多酸四丁基铵盐具有更高的催化活性．底物环己烯的转化率为58．9％，产物环氧环己烷的选择性大于等于99％．同时还对杂多酸催化环氧化环己烯的机理做了初步的探讨．

英文摘要：

The tetra-n-butylammonium salts derivative of six coordination water of trivacant Keggin-type sandwich polyoxometalate [（M^Ⅱ （H2O）3）2 （WO2）2 （BiW9O33）2 ]^10- （M = Ni, Mn, Co） and three coordination water [（M^Ⅱ（H2O））3 （BiW9O33）2]^12- （M = Ni, Mn, Co）were used as catalysts for cyclohexene epoxidation using hydrogen peroxide as oxidant. The catalytic performance of these two catalysts was studied in the different reaction times. The catalytic activity of（[（C4H9）4N]10[（M^Ⅱ（H2O）3）2（WO2）2（BiW9O33）2]（M=Ni,Mn,Co）are superior to [（ C4H9）4N]12 [（M^Ⅱ（ H2O） ） 3 （ BiW9 O33）2]（ M = Ni, Mn, Co）. The best result was achieved with [（C4H9）4N]10[（M^Ⅱ（H2O）3）2（WO3）2（BiW9O33）2]. When the molar ratio of hydrogen peroxide to cyclohexene was 3, the conversion of cyclohexene was 58.9% and selectivity for cyclohexene oxide was 99.9% after 6 h of reaction at 80℃. Discussed the probable mechanisms of cyclohexene epoxidation to cyclohexene oxide catalyzed by heteropoly compounds.
