摘要
研究了以氯苯、CO2 为原料,N,N 二甲基甲酰胺为溶剂,铝为牺牲阳极,不锈钢为阴极,在无隔膜电解池中,水浴温度 5℃下电化学羧化制备苯甲酸。用IR、HPLC、UV-vis对反应产物进行了表征,以分光光度法作定量测定。苯甲酸产率为 21%,电流效率为 60%。
Electrocarboxylation of chlorobenzene with CO_2 in N,N-dimethylformamide was studied.The sacrificial aluminum anode and the stainless steel cathode were used in a diaphragmless cell at 5 ℃ in ice water bath.IR,HPLC and UV-vis were used for qualitative analysis and the ultraviolet spectrophotometric method was used for quantitative determination.The yield of benzoic acid was 21%and the current efficiency was 60%.
