Vacuum Distillation

Vacuum distillation is a method of distillation whereby the pressure above the liquid mixture to be distilled is reduced to less than its vapor pressure (usually less than atmospheric pressure) causing evaporation of the most volatile liquid(s) (those with the lowest boiling points). This distillation method works on the principle that boiling occurs when the vapor pressure of a liquid exceeds the ambient pressure. Vacuum distillation is used with or without heating the mixture.

Famous quotes containing the words vacuum and/or distillation:

    Teenagers who are never required to vacuum are living in one.
    Fred G. Gosman (20th century)

    In this century the writer has carried on a conversation with madness. We might almost say of the twentieth-century writer that he aspires to madness. Some have made it, of course, and they hold special places in our regard. To a writer, madness is a final distillation of self, a final editing down. It’s the drowning out of false voices.
    Don Delillo (b. 1926)
