Apr 20, 2019 Fractional distillation: It is employed for separating two or more volatile liquids having boiling points close to each other eg. acetone (bpt 60C) and methanol (bpt 65C).The vapours of the liquids pass through the fractionating column which provides greater space for their cooling. The vapours of high boiling fractions condense and fall back into distillation flask.

Binary Distillation Weight and Mole Fractions

Continuous Distillation: In a typical distillation column, feed enters the distillation tower at the boiling point. The feed gets in contact with the liquid reflux traveling down the rectification section. The vapors leave the column and are condensed in a total condenser. Liquid is withdrawn and a part of it is used as reflux. The residue from the bottom of the column is withdrawn and is ...

Molecular distillation lowers the boiling point of liquids in a molecular still and is used to separate and remove undesirable molecules such as colorants, or to concentrate heat-sensitive molecules such as fatty acids. Molecular distillation also eliminates the low-boiling, ‘dirty’ top notes, resulting in a refined, super suave aroma.
