在常压下,考察了在PdC1_2-FeCl_3-H_2SO_4-BuOH催化体系中乙炔氧化羰基化合成丁烯,二酸二丁酯的反应动力学。所得结果验证了乙炔形成双金属络合活化机理的合理性,提出了因分子岐化反应而得到顺反异构体产物的反应历程。
Under atmospheric pressure, the reaction kinetics of the oxidative carbonylation of acetylene to butene and dibutyl ester in PdCl_2-FeCl_3-H_2SO_4-BuOH catalyst system was investigated. The obtained results verify the rationality of acetylene formation bimetallic complex activation mechanism, and proposed the reaction process of cis-trans isomer products due to the molecular disproportionation reaction.
