研究了微波辐射下干法氧化苯偶姻生成苯偶酰的反应。结果表明,硅胶和酸性氧化铝是本反应的良好载体,空气是良好的氧化剂。在较短时间内(8～15min)即可获得很高的产率(92％～98％),为一种有效的苯偶姻氧化反应新方法。
The reaction of benzoyl peroxide with benzoyl peroxide under microwave irradiation was studied. The results show that silica gel and acidic alumina are good carriers for the reaction, and air is a good oxidant. In a short period of time (8 ~ 15min) to get a high yield (92% ~ 98%), as a new method of benzoin oxidation.
