摘要 采用液-液相转移催化法合成4-氯二苯基溴甲烷,对影响反应收率的相转移催化剂、催化剂用量、反应温度、反应时间和物料配比各因素进行了研究,确定了反应的最佳条件,收率达85.8%,反应物料的消耗大大降低,反应时间减半。 4-Chlorodiphenylbromomethane was prepared using phase transfer catalysts. The factors affecting the reaction were investigated, including the type and amount of phase transfer catalysts, reaction temperature, reaction time and reagent proportion, The most suitable condition were obtained. Compared to the traditional methods, the product yield was higher (85,8 % ). The amount of reagent used was reduced largely, and the reaction time was shortened by half.
