摘　　要：以冰醋酸为溶剂,硝酸铵为助剂,单质Cu及其氯化物能将苯偶姻氧化成苯偶酰。研究了Cu、CuCl、CuCl2对反应的影响,通过实验得到其最佳反应条件为:2.12 g苯偶姻,1 g硝酸铵,14 mL冰醋酸0.05 g铜丝。收率95%,产物的熔点,及红外光谱与文献一致。Benzil was synthesized from benzoin with Cu and chloride as oxidation, and its structure was characterized by IR. The optimum conditions were obtained as follows： benzoin was 2.12 g, copper 0.05 g, ammonium nitrate 1 g, and glacialacetic acid 14 mlo Under above conditions, the yield was 95%.
