摘要:
为了将多元混合物中的氯代环己烷等分离提纯,采用两步精馏的方法.先将混合液进行常压间歇精馏,蒸去大部分环己烷,环己烯以及少量的杂质,精馏完毕,将塔釜液抽滤,可得产品,视产品纯度再减压精馏塔釜液,直接将氯代环己烷蒸馏出来.考察了精馏过程中的影响因素:压强、回流比、加热量、全回流开工时间.采用变回流比操作,塔顶得到较佳的实验条件为:加热电压160V,全回流30 min,变回流比4.5~3~1.5.提纯氯代环己烷的操作条件:真空度为0.068~0.072 MPa,纯度达到99.06%.
Abstract:
In order to separate and purify the chlorinated cyclohexane in the multi-component mixture, a two-step rectification method is adopted. First carry out atmospheric pressure batch distillation of the mixed liquid, distill most of the cyclohexane, cyclohexene and a small amount of impurities, complete the rectification, and filter the column kettle liquid, and obtain the product, according to the purity of the product, and then vacuum rectification column liquid, directly distill the chlorocyclohexane. The influencing factors in the distillation process were investigated: pressure, reflux ratio, heating amount, and full reflux start time. Using the variable reflux ratio operation, the best experimental conditions obtained at the top of the tower are: heating voltage 160V, full reflux 30 min, variable reflux ratio 4.5~3~1.5.Operating conditions for purification of chlorocyclohexane: vacuum degree is 0.068~0.072 MPa, purity reaches 99.06%.
