About Sublimation and Distillation
Sublimation separates a sublimable solid from non-sublimable impurities by direct conversion between solid and vapour, followed by deposition. Distillation separates liquids through differences in boiling points, including simple, fractional, steam and vacuum distillation, and the choice depends on volatility, miscibility and thermal stability.
