摘要
介绍了几种无水乙醇制备工艺,包括萃取精馏法、共沸精馏法、分子筛吸附法、膜分离法、减压精馏法。简要介绍了各种方法的特点,并对几种工艺进行了对比。
Several kinds of preparation of absolute alcohol was introduced,including the method of extractive distillation,azeotropic distillation,molecular sieve adsorption,membrane separation,reduced pressure distillation method. This paper briefly introduced the characteristics of various methods,the five kinds of process were compared.
