摘要
以添加稀土元素Ce制备的蒙脱土固体酸为催化剂,合成了二芳基乙烷。实验结果表明最佳反应条件如下:苯乙烯与二甲苯摩尔比为1∶7、催化剂用量为12%(苯乙烯质量百分比)、反应时间为3.5 h、反应温度为120℃,此时产率可达83.03%。
Diphenylethane was synthesized by using the montmorillonite solid acid catalyst modified with Ce. The experimental results showed the best conditions were as follows： the molar ratio of styrene to xylol was 1 ： 7 ,the mass of the catalysl was 12%0 of thai of styrene,the reaclion time was 3. 5 h and the experimental lemperature was 120℃,and the product yield could reach 83.03%.
