Dawson型磷钼钒杂多酸催化合成1,3-二噁戊烷的研究

Study on the Catalytic Synthesis of 1,3-Dioxolane over Wells-Dawson type Molybdovanadophosphoric Heteropolyacid

考察了Dawson型磷钼钒杂多酸和各种结构反应底物对1,3 二噁戊烷合成催化活性的影响.研究表明:H6P2Mo17VO62的催化效果最好,反应条件温和,环氧化物的转化率接近100%,1,3 二噁戊烷的选择性在90%以上.

The effects of heteropolyacid catalysts and various structural substrates on the catalytic activity to synthesis 1,3-dioxolane derivatives were investigated. The results indicated that Wells-Dawson Heteropolyacid H_6P_2Mo_(17)VO_(62) is the best catalyst for this reaction with nearly complete conversion of epoxide and excess 90% of selectivity to 1,3-dioxolane.
