distillation in which the liquid distilled is enclosed at a low pressure in order to reduce its boiling point
vacuum distillation in American English
noun
Chemistry
a process of distillation employing a vacuum that by lowering the pressure on a liquid allows volatilization at a lower temperature than normal
