Vacuum Distillation is a process that allows the purification of compounds at a pressure below atmospheric pressure. vacuum distillation is carried out under vacuum to increase the relative volatility of components. vacuum distillation is sometimes referred to as low-temperature distillation.
Vacuum distillation is a method or process to separate components in a mixture at a pressure below atmospheric pressure. Temperature-sensitive materials require vacuum distillation to remove solvents from the mixtures without damaging the products and this technique is used when the components in the mixture have boiling points that are difficult to be achieved or if higher temperatures cause the compounds to be decomposed instead of vaporizing. we require a manometer in vacuum distillation.
