| | Definition: | | \Dis`til*la"tion\, n. [F. distillation, L.
destillatio.]
1. The act of falling in drops, or the act of pouring out in
drops.
2. That which falls in drops. [R.] --Johnson
3. (Chem.) The separation of the volatile parts of a
substance from the more fixed; specifically, the operation
of driving off gas or vapor from volatile liquids or
solids, by heat in a retort or still, and the condensation
of the products as far as possible by a cool receiver,
alembic, or condenser; rectification; vaporization;
condensation; as, the distillation of illuminating gas and
coal, of alcohol from sour mash, or of boric acid in
steam.
Note: The evaporation of water, its condensation into clouds,
and its precipitation as rain, dew, frost, snow, or
hail, is an illustration of natural distillation.
4. The substance extracted by distilling. --Shak.
{Destructive distillation} (Chem.), the distillation,
especially of complex solid substances, so that the
ultimate constituents are separated or evolved in new
compounds, -- usually requiring a high degree of heat; as,
the destructive distillation of soft coal or of wood.
{Dry distillation}, the distillation of substances by
themselves, or without the addition of water or of other
volatile solvent; as, the dry distillation of citric acid.
{Fractional distillation}. (Chem.) See under {Fractional}.

| | Definition: | | A lab technique used to purify a substance, to remove a solvent (a liquid that a substance is dissolved in) from the substance, or to separate two or more components in a liquid mixture. Ideally, this is done by taking advantage of the fact that the different chemicals have different boiling points. The temperature is raised so the chemical with the lowest boiling point boils first, its vapor is shunted out of the flask and towards a different container, and then it is cooled so that it condenses back into a (more purified) liquid. The temperature can then be raised to boil the next chemical, etc., until only the chemical with the highest boiling point remains in the original container. |
