Azeotropic distillation is a type of distillation in which certain components are added to the mixture to improve separation. Water or benzene are usually added to the mixture because they can aid increase the volatility of a chemical.

Can azeotropes be distilled?

An azeotrope is not a range of concentrations that cannot be distilled, but the point at which the activity coefficients of the distillates are crossing one another.

What do you mean by azeotropic distillation?

Definition: A method of separating mixtures based on differences in their volatilities in a boiling liquid mixture. ... This has the effect of changing the volatility of one of liquids in the azeotrope to a greater extent than the other, allowing separation to occur.
