| Abstract: | A novel catalytic system CaCl 2_K 2S 2O 8_CF 3COOH was used for direct carboxylation of ethane to propionic acid.The effect of reaction temperature,reaction time,CO pressure and catalysts were investigated;the optimal conditions for the reaction were determined,the yield of propionic acid could reach 86.0% or so under optimized reaction conditions.A possible reaction mechanision was proposed. |
