"WebAn azeotrope is a mixture of two or more pure compounds (chemicals) in such a ratio that its composition cannot be changed by simple distillation. This is because when an azeotrope is boiled, the resulting vapor has the same ratio of constituents as the original mixture of liquids. Because composition is unchanged by boiling, azeotropes are also … " - High boiling azeotrope
