摘    要:以活性炭负载硫酸作为一种新型便宜和有效的环境友好固体催化剂,催化合成了二苯甲烷.考察了催化剂用量、苯与苄基氯体积比、反应温度以及反应时间对该傅一克反应的影响,得出了最佳反应条件,即m(改性活性炭):m(苯):m(苄基氯)-18:39:4,反应时间为7h,反应温度为80℃.在此条件下,二苯甲烷产率为78%.

关 键 词:二苯甲烷  改性活性炭  催化

Abstract:Diphenylmethane was synthesized in the presence of a new environmentally friendly catalyst H2SO4/carbon. The influences of catalyst's dosage, the volume ratio of benzene with benzyl chloride, temperature and the reaction time on the yield of product have been investigated. The diphenylmethane was obtained in 78o/00 yield under the optimal reaction conditions, rn (catalyst) : m (benzene) : m (benzyl chloride) =18 : 39 : 4, at 80 ℃ for 7 h.
Keywords:diphenylmethane  modified activated carbon  catalyst
