An azeotrope or a constant heating point mixture is a mixture of two or more liquids whose proportions cannot be altered or changed by simple distillation. This happens because when an azeotrope is boiled, the vapour has the same proportions of constituents as the unboiled mixture. Because their composition is unchanged by distillation, azeotropes are also called (especially in older texts) constant boiling point mixtures.

WebP14.1. An azeotrope is a constant-boiling solution in which evaporation causes no change in the composition of the liquid. In other words, the composition of the liquid and gaseous phases must be identical. If the vapors may be assumed to be perfect gases, then the ratio of the two partial pressures is equal to the ratio of the mole fractions ... WebApr 7, 2024 · A mixture of two or more liquids whose proportion cannot be changed by the simple distillation is called Azeotrope. This phenomenon occurs because when the azeotrope is boiled, it produces the vapour, and the proportion of constituents in this vapour and the mixture which is not boiled is the same.
