The action of converting any substance or constituent of a substance into vapour by means of heat, and of again condensing this by refrigeration into the liquid form, by means of an alembic, retort and receiver, or a still and refrigeratory; the extraction of the spirit, essence, or essential oil of any substance by the evaporation and condensation of its liquid solution; and, in a more generalized sense, the operation of separating by means of fire, and in closed vessels, the volatile parts of any substance from the fixed parts, in order to the collection of the products.As shown by the etymology, the original application is to substances of which the distillates are condensed drop by drop into the liquid form; whether for the purpose of extracting the more volatile part of a substance, or of concentrating or purifying a volatile substance such as water by freeing it from matter held in suspension or solution. When no more heat is applied than just suffices to cause the liquid to pass over in drops, the process is called cold distillation. Dry or destructive distillation, the decomposition of a substance by strong heat in a retort, and the collection of the volatile matters evolved, as in the destructive distillation of coal in gas-making. fractional distillation, the separation of two or more volatile liquids having different boiling-points, so that they pass over at different temperatures and can be collected separately, the more volatile first, and the less volatile in order afterwards. distillation by descent (per descensum), in Old Chemistry, the name given to a method in which the fire was applied above, and the distillate drawn off beneath (see descent n. 11). In opposition to this, the ordinary method was called distillation by ascent (per ascensum).
