Azeotropic Distillation

Azeotropic distillation is a specialized technique used to separate components of a mixture that form an azeotrope. An azeotrope is a mixture of two or more liquids that cannot be separated by simple distillation because the vapor has the same composition as the liquid mixture. This method is commonly used in industries like chemicals, pharmaceuticals, and food processing.

How Does It Work?

  1. Formation of Azeotrope: The mixture is heated, and the azeotrope forms when the vapor
    composition matches the liquid composition.
  2.  Addition of Entrainers: To break the azeotrope, a third substance (entrainer) is added to
    alter the volatility of the components.
  3. Distillation: The mixture is distilled, separating the components based on their boiling
    points.
  4. Separation: The entrainer helps isolate the desired component from the azeotropic mixture.
