摘要
本文通过催化剂种类与用量。溶剂、反应温度及时间的筛选与优化,使4,4’-二氯甲基联苯的收率达到87.8％,纯度达到98.0％。同时消除了有害物质二氯甲醚对环境的影响。
By screening and optimizing of reaction conditions, such as : the kinds and quantities of catalyst chosen, solvents, reaction temperatures and times. The yield of 4,4'-dichloromethyl-hiphenyl could be reached as high as 87.8%, the purity >98.0%. The harmful effect of dichloromethyl ether diminished remarkably.
