One of the oldest of all chemical techniques is distillation. An example of distillation in its simplest form is boiling water. Indeed, boiling water and then condensing it on a cold surface is one of the best methods for water purification. With water...

A mixture of two or more liquids that together have a different boiling point than the liquids individually. This property of azeotrope is sometimes used in differential distillation if two liquids being distilled have similar boiling points –...

A mixture of two or more compounds that have a constant boiling point. The composition of the vapor above the azeotropic mixture has the same relative concentration of the compounds as does the boiling liquid. Azeotropic mixtures cannot be separated by...

An azeotrope is a mixture of two or more pure compounds (chemicals) in such a ratio that its composition cannot be changed by simple distillation.[1] This is because when an azeotrope is boiled, the resulting vapor has the same ratio of constituents as...
