the action of purifying a liquid by a process of heating and cooling
another term for destructive distillation.
distillation of a liquid in a current of steam, used especially to purify liquids that are not very volatile and are immiscible with water
a process whereby certain volatile substances vaporize in warm climates and condense in cooler areas, causing the accumulation of pollutants
distillation of a liquid under reduced pressure, enabling it to boil at a lower temperature than normal
decomposition of a solid by heating it in a closed container and collecting the volatile constituents given off
separation of a liquid mixture into fractions differing in boiling point (and hence chemical composition) by means of distillation, typically using a fractionating column
