fractional distillation
A process by which a chemical compound is separated into components by distillation. In fractional distillation the compound is heated and, as each of its constituent components comes to a boil, its vapors are separated and cooled, so it can be removed in its pure form. Fractional distillation is used to refine petroleum. See also distillation.
