Impure organic liquid having soluble impurities can be purified by fractional distillation.
1. In crystallization, the principle involved in seperation of compounds is based on difference in solubility of impurities at different temperatures.
2. In distillation, mixture is separated on the basis of boiling points.
3. Different impurities have different boiling points.
4. Simple distillation simply removes the mixture by boiling.
5. In fractional distillation, mixture with less difference in boiling points are seperated
6. To achieve this, fractional column is set up, which allows movement of only one type of liquid.
7. Boiled liquids in distillation are condensed in seperate flasks to get the purified product.
