摘　　要：以加氢尾油、氯气为原料,浓硫酸为酸洗剂,白土为吸附剂,通过光氯化法合成了氯化石蜡-52。物料配比为m(硫酸):m(白土):m(加氢尾油)=8:6:100,酸洗处理的温度为100℃,酸洗时间为2 h,静置时间为1 h。白土吸附温度为120℃,吸附时间为2 h,静置时间为2 h。氯化反应温度控制在70～80℃,氯化石蜡产物含量≥52%。Chlorinated paraffin-52 was prepared by photochemical chlorination of hydrocracking tail oil with chorine, using H2SO4 as acid washing solution, bentonite as absorbent. The optimal conditions were found as follows： m（H2SO4） / re（bentonite） / m（chloroparaffin） = 8 ： 6 ： 100, acid washing temperature 100℃, washing 2 h,keeping at static condition for 1h, bentonite absorption temperature 120℃, absorbing 2 h,keeping at static condition for 2 h, chlorination reaction temperature from 70 to 80℃. Under these conditions, chloroparaffin could be obtained with 52% content.
