Azeotrope

Vapour–liquid equilibrium of 2-propanol/water showing azeotropic behaviour

Azeotropes are the mixtures of liquids which boil at a constant temperature. Azeotropes may be called constant boiling point mixtures or azeotropic mixtures.[1]

Their proportions cannot be altered by simple distillation.

Types[change | change source]

Azeotropes are classified into two types

  1. Minimum boiling azeotrope
  2. Maximum boiling azeotrope
