摘　　要：对异佛尔酮气固相催化芳构化合成3,5-二甲基苯酚反应过程进行了研究。通过对不同反应时段的反应产物分布的分析,对该反应过程进行了推测。试验表明主要涉及两个并联反应:1)异佛尔酮的酮酚重排过程,主要生成3,5-二甲基苯酚;2)异佛尔酮的分解过程,可以生成多种副产物。为反应机理的研究和适宜反应条件的确定提供了一定的试验基础。Reaction network in catalytic aromatization of isophorone to 3,5-xylenol was investigated in this paper. The concentration distributions of reaction products with different reaction time were analyzed and the detailed reaction network was speculated. It was indicated that this reaction could be classified into two major processes. One is dienone-phenol re-arrangement of isophorone to 3,5-xylenol, the other is decomposition of isophorone to many byproducts. This work provided the foundation for researching the reaction mechanism and optimizing reaction conditions.
