补充资料:α,α,α,α',α',α'-六氯对二甲苯
分子式:C8H4Cl6
分子量:312.84
CAS号:68-36-0

性质:白色针状或粉末状结晶。熔点108-110℃。溶于二甲苯、石油醚、乙醇、植物油,不溶于水。无味,有特殊臭味,遇光、碱会缓慢分解而呈酸性。

制备方法:以混二甲苯为原料,先用98%硫酸磺化,使间二甲苯生成间二甲苯磺酸盐。从磺化反应物中分离出含邻、对二甲苯的油层,水洗、干燥,减压蒸馏出邻、对二甲苯。间二甲苯磺酸盐经水解可得副产品间二甲苯。由邻、对二甲苯经氯化即得1,4-双(三氯甲基)苯:在反应锅中投入邻、对二甲苯,再加入过氧化苯甲酰和三乙醇胺。加热到70℃后,在光照射下导入氯气,于70-80℃反应6h,再升温至100-120℃继续反应,至反应液相对密度达到1.560-1.580(65℃),即为反应终点,停止通氯,减压脱除余氯。降温至5℃,过滤,洗涤得粗品,重结晶,活性炭脱色得成品。

用途:抗血吸虫病药物。对肝吸虫病、阿米巴原虫病、疟疾以及肠道线虫有一定疗效。但对神经系统的不良反应较多见,且延迟反应持续较久。
