摘　　要：用高效液相色谱法优化苯与对氯氯苄烷基化反应催化剂刘红霞张书胜袁倬斌＊（郑州大学分析测试中心郑州）（中国科学技术大学研究生院北京１０００３９）关键词氯－二苯甲烷，制备，三氯化铝，硝基苯，硝基乙烷，高效液相色谱法１９９７－０３－３１收稿，１９９７－０９－...The highperformance liquid chromatography(HPLC) has been used for quantitative determination of o,m,pchlorodiphenylmethane(CDPM) from the reaction products of benzene with pchlorobenzyl chloride for pCDPM preparation. The detection limits of the method for o,m,pCDPM were 035, 040 and 032 mg/L, respectively. The method was applied to gain the optimum constitution of the catalysts used in the preparation. The results showed that nitro compounds could prevent the decomposition of diphenylmethane and its chloride. The yield of pCDPM was higher than 96%, when AlCl3(4 g)+EtNO2(15 mL) were used as catalyst.
