乙酸丁酯和正丁醇是两种重要的有机化工原料,广泛应用在化工和制药行业中。在青霉素提取过程中产生大量的含乙酸丁酯、正丁醇、水的混合物,如何将其分离,有实际的意义。本文介绍皂化处理方法和恒沸精馏分离方法,通过利用3A分子筛优化恒沸精馏工艺过程,从而达到节能降耗20%的目的。 Butyl acetate and n-butanol are two important organic chemical raw materials, widely used in chemical and pharmaceutical industries. In penicillin extraction process produces a large number of butyl acetate, n-butanol, water mixture, how to separate, of practical significance. This article describes the saponification method and azeotropic distillation separation method, through the use of 3A molecular sieve optimization azeotropic distillation process, so as to achieve the purpose of saving 20% ​​energy.
