The method of liquid phase rearrangement of styrene oxide to phenylacetaldehyde catalyzed by SAStype solid acids and molecular sieves was studied.

研究了SAS型固体种分子筛上氧化苯乙烯液相重排成苯乙醛的应,考察了催化剂的活性、选择性稳定性。

The results showed that the main product was benzaldehyde and a little by-products were styrene oxide and phenylacetaldehyde.

发艺中主要生成苯甲醛，少量副产物是环氧苯乙烷苯乙醛等。
