摘要
在有隔膜电解槽中 ,Cu2 +离子为电解媒质 ,铂作阳极 ,石墨为阴极 ,对苯的间接电氧化进行了研究。结果表明 ,苯的间接电氧化产物受pH、硫酸铜浓度、通氧速度等因素的影响。在pH 1 3、硫酸铜浓度 1 0 0mmol/L和通氧速度 5ml/min时 ,主要产物是苯酚 ;在pH 3 5、硫酸铜浓度 5mmol/L和通氧速度 1 0ml/min时 ,主要产物是对苯二酚。
The indirect electro-oxidation of benzene was studied in a divided electric cell, with Cu2+ as electrolytic medium, Pt as anode and graphite as cathode. The results showed that the primary product was phenol when pH was 1.3 with CuSO4 concentration 100mmol/L and oxygen velocity 5 ml/min, or the primary product was quinol when pH was 3.5 with CuSO4 concentration 5mmol/L and oxygen velocity 10 ml/min.
