Process useful for separating two or more substances of a mixture that exploits the difference between their boiling points.

The distillation system can be used to separate complex mixtures or to purify individual substances. In any case, distillation involves the transition of a substance from a liquid to a gaseous state.

Following here the most significant transition processes:

SOLID / LIQUID = MELTING

LIQUID / SOLID = SOLIDIFICATION

SOLID / GASEOUS = SUBLIMATION

GASEOUS / SOLID = FROSTING

LIQUID / GASEOUS = EVAPORATION – DISTILLATION

GASEOUS / LIQUID = CONDENSATION
