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.

- Azeotrope

Azeotropes are one kind of mixture that usually poses considerable difficulties regarding the separation processes required to obtain their constituents (physical or chemical processes or, even a blend of them).
