- simple distillation
- fractional distillation
- steam distillation
- vacuum distillation.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Styrene is primarily a synthetic chemical. It is also known as vinylbenzene,ethenylbenzene, cinnamene or phenylethylene. It's a colorless liquid that evaporates easily and has a sweet smell. Styrene can be purified by Vacuum distillation. Vacuum distillation is the process of lowering the pressure in the column above the solvent to less than the vapor pressure of the mixture, creating a vacuum, and causing the elements with lower vapor pressures to evaporate off.

Concepts Used:
Purification of Organic Compounds
We commonly use these methods for the purification of substances:
- Simple crystallization - The most common method that we use to purify organic solids.
- Fractional crystallization - It is the process of separation of different components of a mixture by repeated crystallisations.
- Sublimation - Certain organic solids on heating directly change from solid to vapor state without passing through a liquid state. These substances are sublimable. This process is sublimation.
- Simple distillation - It is the joint process of vaporization and condensation.
- Fractional distillation - It is the process to separate a mixture of two or more miscible liquids which have boiling points close to each other
- Distillation under reduced pressure
- Steam distillation
- Azeotropic distillation
