本文在气相色谱分析的基础上,研究了1,2,3,6-四氢化邻苯二甲酸酐在各种路易士酸催化下的反应情况,并对以对甲苯磺酸为催化剂的反应进程提出了通过碳正离子中间体的可能机理. Based on the gas chromatographic analysis, the reaction conditions of 1,2,3,6-tetrahydrophthalic anhydride catalyzed by various Lewis acids were studied. The reaction process of p-toluenesulfonic acid as catalyst A possible mechanism for the passage of carbenium intermediates was proposed.
