摘　　要：研究了在N2气氛和升华处理的无水A lC l3催化作用下,苯与草酰氯反应。反应产物的GC/MS检测结果表明,苯甲酸(28.4%)和二苯甲酮(33.4%)是主要产物,而二苯乙二酮的量却很少,推测该反应经历了碳正离子亲电取代-自由基取代反应历程。并讨论了未处理的和升华处理的A lC l3活性对产物组成的影响。Under N2 atmosphere and the catalyst of anhydrous AlCl3 sublimated, the reaction of benzene with oxalyl chloride was investigated. The analysis of the reaction products with GC / MS shows that the main products are benzoic acid （28.4%）and benzophenone （33.4%） while dibenzyl ethanedinone is scanty. So it is believed that the reaction proceeds via carbon cation electrophilic substitution reaction- free radical substitution reaction pathway. The influence of the activity of AlCl3 on the composition of products has been discussed,too.
