| Abstract: | 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. |
