| 摘 要： | 研究了在N2气氛和升华处理的无水AlCl3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AlCl，活性对产物组成的影响。

| Abstract: | Under N_(2) atmosphere and the catalyst of anhydrous AlCl_(3) 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 AlCl_(3) on the composition of products has been discussed,too. |
