| 摘 要： | 以1,4-二氯甲氧基丁烷(BCMB)为氯甲基化试剂,使用无水氯化锌作催化剂,在丙酮作溶剂的条件下对酚醛树脂(PF)进行了氯甲基化,制得氯甲基酚醛树脂(CMPF).考察了各种因素对氯甲基化反应的影响,确定了较佳反应条件为PF∶BCMB∶ZnCl2=1∶4.42∶0.58(质量比),58℃反应6h,可得到氯甲基化程度为65%的CMPF.通过红外光谱法和佛而哈德分析法表征了产物的化学结构与组成,并对反应机理进行探讨.

| Abstract: | In this paper, we made 1, 4 -bis（chloromethoxy） butane （BCMB） as the chlorornethylation reagent and adopted zinc chloride catalyst, in acetone solvent to carry out the PF chloromethylation reaction, made the ehloromethylated phenolic -formaldehyde resion（CMPF）. The effects of various factors on the ehlo- romethylation reaction were examined, the better condition was as followed ： PF ： BCMB ： ZnC12 = 1 ： 4.42 ： 0. 58（quality rate）, temperature is 58℃, time is 6h, then we obationed the CMPF which chloromethylation de- gree is 65%. The chemical structure and composition of the product were characterized with infrared spectrum and Volhard method. Then the reaction mechanism was discussed. |
