摘　　要：合成一种新型N-甲基吗啉钨酸盐[Mor1,n]Na W2O11(n=2,5,8),并考察了在以30%H2O2为氧化剂,乙腈为反应溶剂,[Mor1,2]Na W2O11为催化剂的催化环氧化环辛烯的反应体系中反应溶剂的量、催化剂的量、氧化剂的量和反应温度的变化对产率的影响,最终确定了最佳反应条件:反应温度70℃,环辛烯1 mmol,催化剂量30μmol,H2O2(30%)量2 mmol,乙腈0.5 m L,反应6 h,产率96%。The tungsten （[Mor1,n]NaW2O11） （n=2,5,8）were synthesized and applied in epoxidation of cyclo-pentene. The effects of different amounts of catalyst, oxidant, reaction solovent and reaction time on the yield were systematically studied. The optimum reaction conditions of epoxidation was suggested：at 70 ℃, n（ catalyst）：n（ cy-clopentene）：n（H2O2（30%）） =3∶100∶200, reaction solovent 0. 5 mL, for 6 h, under which the cyclopentene yiled was more than 96 % with [ Mor1,2 ] NaW2 O11 as catalyst.
