1·Recent development in hydroformylation of ethene to propanal by catalytic synthesis is introduced in this paper.

本文综述了采用均相催化剂、均相固载化催化剂以及多相催化剂催化合成丙醛的研究成果。

2·The preparation of 2,2-dimethyl-3-hydroxy propanal from the condensation of formaldehyde and i-butyraldehyde by using triethylamine as catalyst was studied.

以异丁醛和甲醛为原料，三乙胺为催化剂，羟醛缩合法合成了2，2-二甲基-3-羟基丙醛。
