Can the components of an azeotropic mixture be separated by fractional distillation?
Question:
Can the components of an azeotropic mixture be separated by fractional distillation?
Fractional Distillation:
Miscible liquids are separated via a type of distillation called fractional distillation. The mixture is typically divided into parts after a series of distillations and condensations. When the combination is heated to a specific temperature where some of the mixtures begin to evaporate, the separation takes place.
