Don't Let a Second Liquid Phase Faze You

摘要

TWO LIQUID phases can form inside distillation towers in specific systems. Typically one phase is ionic, usually aqueous, and the other nonionic, generally oil or hydrocarbon-based. Either phase may be the major component. Water entrapment in hydrocarbon columns is a common example of an ionic liquid phase as the second phase. Fusel oils in ethanol distillation (see: "Cure Column Hiccups," www.ChemicalPro-cessing.com/articles/2005/608/) typifies a relatively nonionic liquid phase occurring in a mostly ionic system.
