In 95.63% ethanol and 4.37% water (by mass) mixture, the boiling point of ethanol is 78.4 °C and the boiling point of water is 100 °C. They form an azeotrope and the boiling point of the azeotrope is 78.2 °C which is lower than both the component, hence it is a minimum boiling azeotrope. … WebThe boiling point of ethanol is 78.5°C and water is 100 as everyone knows, but at the azeotropic point the combination of water and ethanol boils at 78.15°C which isn't a lot of difference, but enough to prevent increasing the ethanol level in the distillate without either using vacuum distillation, or adding chemicals to break the azeotrope ... crouse hospital internists WebJan 1, 2016 · A typical example is the distillation of mixtures of water-ethanol. By classic distillation, the distillate contains 95 % of alcohol (pure boiling temperature, 78.4 °C) and 5 % of water (pure boiling temperature, 100 °C), and no further increments in ethanol purity can be reached, because this mixture boils, as a unique compound, at 78.17 °C.
