John Goodson 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.
