What Is Distillation? Principles and Uses - ThoughtCo

Jan 29, 2020 Distillation is the process of separating components of a mixture based on different boiling points. Examples of uses of distillation include purification of alcohol, desalination, crude oil refining, and making liquefied gases from air. Humans have been using distillation since at least 3000 BC in the Indus valley.
