Definitions of distillation

  1. a purified liquid produced by condensation from a vapor during distilling; the product of distilling
  2. That which falls in drops.
  3. 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.
  4. The substance extracted by distilling.
  5. The process of heating and evaporating to produce pure spirit; the substance so obtained.
  6. Act or process of distilling: that which is distilled.
  7. The act or product of distilling.
  8. The act of distilling; that which distils; the process of extracting spirit from a substance by means of evaporation and subsequent condensation into drops; the process of obtaining a substance pure, or of refining by that means; rectification; the substance obtained by distilling. Dry distillation, the distillation of substances per se, or without the addition of water. Destructive distillation, the distillation of substances at very high temperatures, so that the ultimate elements are separated or evolved in new combinations. Fractional distillation, the separating of the volatile elements of a compound by so moderating the heat that the more volatile shall be distilled off in succession from the less volatile.
  9. The manufacture of ardent spirits or alcoholic liquors from grain, & c.; the operation of extracting a spirit from any substance by evaporation and condensation.
