摘要
经傅－克烷基化反应合成了四甲基二苯乙烷，讨论了各反应条件对反应的影响，得出了最佳反应条件：ｎ（邻二甲基）：ｎ（１，２－二氯乙烷）：ｎ（无水三氯化铝）为１０：１：１．８（ｍｏｌ：ｍｏｌ：ｍｏｌ）反应温度，８０±２℃，反应时间２～３ｈ，反应收率达到７８％，产品纯度为９６．５％以上。
1.2-Bis(3,4-dimethyl phenyl)ethane was synthesized via Fridel-Crafs reaction.The reaction conditions were discussed and the optimum condition was obtained:n(1,2-dimethylbenzene):n(1,2-dichloroethane):n(anhydrous aluminum chloride),10:1:1.8(mol:mol:mol);reaction temperature,80±2℃;rmction time,2~3h.The yield reached 78% andthe purity of target product was above 96.5%.
