WebFor example, ethyl alcohol and water form a binary azeotrope at 0.89 mole fraction alcohol, so that this is the richest alcohol solution that can be recovered by simple distillation. Addition of benzene as an azeotropic agent yields a distillate product consisting of a ternary azeotrope. Thebottoms（釜底产物）is the desired pure alcohol. WebTHF solution is produced, which have to be dehydrated to 99.9%mol THF (BASF, 2001), for the product to be commercially attractive. Though, THF-Water mixture has an azeotrope …
Web28 Dec 2016 · The separation of two systems containing minimum boiling azeotropes (acetone—methanol and tetrahydrofuran (THF)—water) was performed using extractive distillation with a heavy boiling mixed entrainer consisting of two compounds.

Ethanol boils at 78.4°C, water boils at 100°C, but the azeotrope boils at 78.1°C, which is lower than either of its constituents. Indeed 78.1°C is the minimum temperature at which any ethanol/water solution can boil. software engineer facebook salary menlo park
