摘　　要：为了对某型发烟剂中的六氯乙烷进行分离回收,基于Box-Behnken中心组合设计实验,探究了料液比、超声功率、浸取时间、搅拌速度和温度等工艺参数对于六氯乙烷浸取率的影响,通过响应曲面法研究了二氯甲烷浸取六氯乙烷的分离工艺,模拟得到了二次多项式回归方程的预测模型。结果表明,各试验因子与六氯乙烷的浸取率之间满足二次方程模型。料液比为1∶30,超声功率为960 W,浸取时间为2. 0 h,温度30℃是浸取六氯乙烷的最优工艺条件。利用该工艺六氯乙烷浸取率达93. 27%,回收浸取液二氯甲烷的回收率为93. 30%。In order to separate and recover hexachloroethane from a certain smoking composition, the effects of parameters such as material-liquid ratio, ultrasonic power, leaching time, stirring speed and temperature on the leaching rate of hexachloroethane were discussed based on Box-Behnken central composite design experiment. The separation process of hexachloroethane from dichloromethane was studied by response surface methodology (RSM). The predictive model of quadratic polynomial regression equation was obtained. The results show that the two factor equation between the experimental factors and the leaching rate of hexaethane is satisfactory. The optimum technological conditions for leaching hexachloroethane are as follows: the ratio of material to liquid is 1 ∶ 30, the ultrasonic power is 960 W, the leaching time is 2.0 h,and the temperature is 30 ℃. Using this technology, the amount of hexaethane extracted is 93.27%, and the rate of dichloromethane from the leaching solution is 93.30%.
