摘　　要：以联苯、多聚甲醛为起始原料,氯化锌/H2O为催化剂,在氯化氢的存在下经氯甲基化反应,得到了4,4’-二氯甲基联苯。讨论了反应温度和时间对反应产率及产品纯度的影响。并利用气相色谱质谱联用仪对产物中的杂质进行了定性分析。4,4’-Dichloromethyl biphenyl was synthesized through chloromethylation of biphenyl, starting with biphenyl and paraformaldehyde as raw materials, zinc chloride/H 2O as catalyst in the presence of hydrogen chloride. The factors such as reaction temperature and reaction time influencing on reaction yield and purity were discussed. And the impurities in product were analyzed by GC-Mass.
