Study Notes
Distillation
- Distillation is a method of separating components from a liquid mixture based on differences in boiling points and distribution between liquid and gas phases.
Aim of Distillation
- Purify liquid organic substances
- Determine the boiling point
- Separate liquid organic substances from each other or from a solid compound
Types of Distillation
- Simple distillation: used for separation of liquids with boiling points between 30°C to 150°C, stable to heat
- Vacuum distillation (Distillation under reduced pressure): used for separation of liquids with high boiling points or unstable to heat
- Steam distillation: used for separation of water immiscible compounds of low volatility from non-volatile tarry products
- Fractional distillation: used to separate mixtures with components having boiling points differing by only a few degrees, employs a fractionating column
Additional Facts
- Distillation can be used for purification of liquid organic compounds by conversion to the vapor state with heat and subsequent condensation to the liquid state
- Fractional distillation involves collecting separate fractions according to controlled boiling ranges during the distillation of a mixture of substances
