摘要
采用一种新型的催化体系CaCl2·2H2O/K2S2O8/CF3COOH,将丙烷直接羰基化反应合成异丁酸,考察了反应过程中温度、反应时间、CO压力和催化剂等因素对反应收率的影响;选择了反应所需的最优化条件,在此优化条件下,异丁酸的收率可达到48.8%左右;同时给出了可能的反应机理。
A novel catalytic system CaCl_2·2H_2O/K_2S_2O_8/CF_3COOH was used for direct carboxylation of propane to give isobutyric acid. The effects of reaction temperature、reaction time、CO pressure and catalyst were investigated. The optimized condtions for the reaction were determined. The yield of isopropyl acid can be 48.8% or so under the optimized reaction conditions. A possible reaction mechanism was proposed.
