摘　　要：采用氧化铁催化氯苄与甲苯的Ｆｒｉｅｄｅｌ－Ｃｒａｆｔｓ反应生成一苄基甲苯（ＭＢＴ）和二苄基甲苯（ＤＢＴ），当甲苯与氯苄的摩尔比为６１，催化剂用量为每摩尔氯苄１．５克及１００℃下反应６小时时，产品收率达９５％．得到的ＭＢＴ和ＤＢＴ热稳定性好，操作温度范围广，无腐蚀性和怪味。Monobenzyltoluene(MBT) and dibenzyltoluene(DBT) were prepared from benzylchloride and toluene via Friedel Crafts Reaction,by the catalysis of ferric oxide.The yield is 95%,when the mole ratio of toluene to benzylchloride is 6∶1,the quantity of the catalyst used is 1.5 gram per mole benzylchloide and the reaction time is 6 hours at 100 ℃. The obtained MBT and DBT have good heat stabilities,broad range of operating temperature and neither corrosion behaviors nor odors.They are fine heat conducting oil with good comprehensive properties.
