Novel approach to predict the azeotropy at any pressure using classification by subgroups [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2012 Distillation is one of the dominating separation processes, but there are some problems as inseparable mixtures areformed in some cases. This phenomenon is called as azeotropy.

SeparationsSince H2O and Ethylene Glycol Monomethyl Ether (EM) form a minimum-boiling azeotrope, 1-pentanol, 1-hexanol, and 1-heptanol are selected as entrainers to separate the azeotropic mixture (H2O/EM) using azeotropic distillation.

Separation of Alcohol-Ester Binary Mixtures by Pervaporation
Eurasian Chemico-Technological Journal, 1999 In this study, the pervaporation behavior of azeotrope forming methanol-methyl acetate and ethanol-ethyl acetate binary mixtures at different compositions was investigated at 30 and 45 °C using PE-based films having different thickness, compositions and

The Methanol-Trimethoxyborane Azeotrope as a Solvent [PDF]
, 1977 The methanol-trimethoxyborane azeotrope is an ea.sily prepa. red solvent of strong H-bond donor and weak H-bond acceptor properties. It has a low viscosity and low boiling point, and is completely transparent in the visible and uv at wave lengths ...

Ionic-Liquid Based Separation of Azeotropic Mixtures
Chemical Engineering Transactions, 2014 A methodology for the screening of ionic liquids (ILs) as entrainers for ILs-based separation processes in binary aqueous azeotropic systems (e.g., water + ethanol and water + isopropanol) is presented.

Infinite/infinite analysis as a tool for an early oriented synthesis of a reactive pressure swing distillation [PDF]
, 2007 The study contributes to the characterization of an original reactive pressure swing distillation system. The methyl acetate (MeAc) transesterification with ethanol (EtOH) to produce methanol (MeOH) and ethyl acetate (EtAc) is shown as illustrative ...
