Extractive distillation - Wikipedia
网页Extractive distillation is defined as distillation in the presence of a miscible, high-boiling, relatively non-volatile component, the solvent, that forms no azeotrope with the other components in the mixture. The method is used for mixtures having a low value of relative volatility, nearing unity.
Extractive distillation: What is it and when should it be used?
网页2021年10月27日 · Extractive distillation is a powerful tool to separate close-boiling mixtures or azeotropic mixtures. It can make it easier to keep the solvent in liquid phase and require less processing versus azeotropic distillation where the solvent must be condensed before being returned to the initial column.

Extractive Distillation: Definition & Process - Vaia
网页Extractive distillation is a pivotal technique in chemical engineering for separating mixtures with similar boiling points. This method requires the addition of an entrainer, which selectively interacts with one of the components, modifying the relative volatility and thus facilitating the separation process.
