The Comparison of Efficiency of Simple Versus Fractional Distillation in the Separation of
Miscible Liquids
Introduction:
The process of distillation is used in separating two substances of differing boiling points
or volatility.
In the process, a liquid is heated to boil, creating vapor, which is then isolated and
allowed to cool and condense as a liquid again, collecting as distillate.
The two types of distillation used in this experiment include simple distillation and
fractional distillation.
Liquids having boiling points with a difference of at least 100°C may be
separated by use of simple distillation.
If a liquid mixture is composed of miscible, volatile
components with a boiling point having a difference of less than 100°C, it must be separated
using fractional distillation.
Fractional distillation provides for repeated distillation by increasing
the surface area using a fractionating column between the distillation pot and distillation head, in
order to better separate the different compounds.
