Reaction of Selective Oxidation of Toluene in Supercritical Carbon Dioxide
The solubility of reactants and products were studied in scCO2,and the results showed that the toluene had a high solubility in supercritical carbon dioxide,and toluene-CO2 system could form single phase under the reaction condition.The solubility of benzyl alcohol,benzaldehyde,and benzoic acid in supercritical carbon dioxide reduced with the polarity enhanced.The synthesis of benzaldehyde could be realized in higher selectivity due to the different solubility of the oxidation products.Furthermore,the effect of reaction time,pressure,temperature,and the molar ratio of toluene and oxygen on the reaction selectivity were also studied.
