Description
Simple distillation:
Simple distillation is a method used for the separation of components of a mixture containing two miscible liquids that boil without decomposition and have sufficient differences in their boiling points.
The distillation process involves heating a liquid to its boiling points and transferring the vapours into the cold portion of the apparatus, then condensing the vapours and collecting the condensed liquid in a container. In this process, when the temperature of a liquid rises, the vapour pressure of the liquid increases. When the vapour pressure of the liquid and the atmospheric pressure reaches the same level, the liquid passes into its vapour state. The vapours pass over the heated portion of the apparatus until they come into contact with the cold surface of the water-cooled condenser. When the vapour cools, it condenses and passes down the condenser and is collected into a receiver through the vacuum adapter.
Applications:
- Separation of acetone and water.
- Distillation of alcohol.
Fractional distillation:
Fractional distillation is used for the separation of a mixture of two or more miscible liquids for which the difference in boiling points is less than 25K. The apparatus for fractional distillation is similar to that of simple distillation, except that a fractionating column is fitted in between the distillation flask and the condenser.
A simple fractionating column is a tube packed with glass beads. The beads provide a surface for the vapours to cool and condense repeatedly. When vapours of a mixture are passed through the fractionating column, because of the repeated condensation and evaporation, the vapours of the liquid with the lower boiling point first pass out of the fractionating column, condense and are collected in the receiver flask. The other liquid, with a slightly higher boiling point, can be collected similarly in another receiver flask.
Applications:
- Separation of different fractions from petroleum products.
- Separation of a mixture of methanol and ethanol.
