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甲醛，少量副产物是环氧和醛。

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型和几种分子筛上氧化烯液相重排成醛的反应,考察了催化剂的活性、选择性和和稳定性。
