Webphenol: [noun] a corrosive poisonous crystalline acidic compound C6H5OH present in the tars of coal and wood that in dilute solution is used as a disinfectant. WebThe boiling point of this mixture is 78.2°C, compared with the boiling point of pure ethanol at 78.5°C, and water at 100°C. You might think that this 0.3°C doesn't matter much, but it has huge implications for the separation of ethanol / water mixtures. The next diagram shows the boiling point / composition curve for ethanol / water mixtures. geoff latham

WebJul 4, 2008 · The normal boiling points of the two pure components are 329.4 and 334.3 K, while the azeotropic boils at 337.6 K at 1 atm with a composition of 34.09 mol % acetone. A two-column extractive distillation process is used with dimethyl sulfoxide as the solvent. WebAn example is 95.63% ethanol and 4.37% water (by mass), which boils at 78.2℃. Ethanol’s boiling point is 78.4℃, and water has a boiling point of 100℃ but the azeotrope boils at 78.2℃. Maximum Boiling Azeotrope. These mixtures have a boiling point greater than their respective constituents.
