azeotropic distillation

基本解释

A topic of great practical and particular industrial interest in recent years has been three-phase azeotropic distillation or heteroazeotropic distillation.
在工业上，三相共沸精馏过程或称之为非均相恒沸精馏过程在近年来逐渐表现出其特殊应用和巨大的实用价值。
By controlling the hydration of alkoxide, and with n-butanol azeotropic distillation and ethanol rinsing methods, the preparation process of superfine titania powder was investigated in detail.
利用控制醇盐水解的方法，分别采用正丁醇共沸蒸馏和乙醇洗涤这两种工艺，详细研究了超细二氧化钛粉体的制备过程。
TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation.
透射电镜分析结果表明，直接加热脱去水或正丁醇会使电气石超细颗粒发生硬团聚，而共沸蒸馏法则可有效防止硬团聚的产生；

共沸精馏
In this paper,the heterogeneous azeotropic distillation was used to separate glycol and 1,2-propanediol with ethylbenzene,mixed xylene and cumene as azeotropic agent,respectively. Combining with the selectivity of azeotropic agent and the azeotropic point of azeotropic agent,suitable azeotropic agent was determined.
本文通过非均相共沸精馏的方法采用乙苯、混合二甲苯、异丙苯三种共沸剂进行实验,结合共沸剂的选择性和共沸物的共沸点来确定共沸剂。
