摘　　要：采用MD-S80短程蒸馏设备分离邻苯二甲酸二甲酯(DMP)和邻苯二甲酸二丁酯(DBP),考察了蒸馏温度、蒸馏压力、刮膜转速、进料速率等实验条件对蒸馏的影响。研究表明降低蒸馏温度、刮板转速和进料速率都有利于轻组分在馏出物富集,但馏出物减少;提高蒸馏压力有利于轻组分在馏出物中富集,但馏出物减少。Dimethyl phthalate （DMP） and dibutyl phthalate （DBP） were separated by the MD-S80 short-path distillation equipment. The effects of distillation temperature, operating pressure, wiper velocity, and feed rate were discussed. The results showed that the distillate amount was reduced and the light component was enriched with a decreasing distillation temperature, feed rate, and wiper velocity or with an increasing operating pressure.
