介绍苯和苯甲醇在环境友好型催化剂硫酸亚铈的催化下合成二苯甲烷,研究了催化剂用量、反应时间对该傅克反应的影响.实验结果表明,该催化剂具有良好的催化活性,实验过程简单,无腐蚀,无废水污染.表1,参4.

To study the synthesis of diphenylmethane from benzene and benzyl alcohol in the presence of an environmentally friendly catalyst Ce2 （ SO4 ） 3- Some factors of the reaction such as the amount of catalyst used and reaction temperature have been investigated in this paper. The results obtained indicated that Ce2 （SO4 ）3 possessed a fairy high catalytic activity for Friedel - Crafts alkylation reaction. The process was characterized by simplicity of reaction, non- corrosion and absence of pollution, 1 tab. ,4refs.
