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

发现该工艺中主要生成苯甲醛，少量副产物是环氧苯苯醛。

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酸几种分子筛上氧化苯烯液相重排成苯醛的反应,考察了催化剂的活性、选择性稳定性。
