distillation
Volatilization of a liquid by heat and subsequent condensation of the vapor; a means of separating the volatile from the nonvolatile, or the more volatile from the less volatile, part of a liquid mixture. [L. de-(di-)stillo, pp. -atus, to drop down]
- destructive d. SYN: dry d..
- dry d. submission of an organic substance to heat in a closed vessel so that oxygen is absent and combustion prevented, with the objective of effecting its decomposition with release of volatile constituents and the formation of new substances. SYN: destructive d..
- fractional d. d. of a compound liquid at varying degrees of heat whereby the components of different boiling points are collected separately.
- molecular d. d. in high vacuum, intended to make possible use of low temperatures to minimize damage to thermally labile molecules that would be decomposed by boiling at higher temperatures.
