共沸蒸馏

化学中,共沸点蒸馏指蒸馏中破坏共沸组成进行蒸馏或分馏的一系列技术。在化学工程中,共沸蒸馏 通常指的是某种加入一种组分以产生一种新的,非均相低沸点共沸点物的技术,(例如产生两种不能互溶的液体相),如在水和乙醇中加入苯。这一加入一种能导致分相的共沸剂的操作即是工业上的共沸蒸馏操作方法中的一部分,或是与其的结合。在某种意义上,加入一种共沸剂与萃取蒸馏是类似的。

Azeotropic distillation 共沸蒸馏

Phase diagram(left) and process flow diagram (right) of an apparatus for the azeotropic distillation with material separation agent. In this case the phase diagram includes a zone where components are not miscible, so following the condensation of the azeotrope, it is possible to separate the liquid components through decantation.

In chemistry, azeotropic distillation is any of a range of techniques used to break an azeotrope in distillation. In chemical engineering, azeotropic distillation usually refers to the specific technique of adding another component to generate a new, lower-boiling azeotrope that is heterogeneous (e.g. producing two, immiscible liquid phases), such as the example below with the addition of benzene to water and ethanol. This practice of adding an entrainer which forms a separate phase is a specific sub-set of (industrial) azeotropic distillation methods, or combination thereof. In some senses, adding an entrainer is similar to extractive distillation.
