Question

difference between fractional distillation and steam distillation.

Answer 1

Differences between Fractional distillation and Steam distillation:

Fractional distillation	Steam distillation
1. It is used for the miscible liquids with a difference of 10K in b.pt.	1. It is used for both solids or liquid immiscible organic compounds .
2.It involves repeated distillation and condensation.	2. It involves distillation at high temperature and condensation at low temperature.
3. The components should be volatile.	3. The components should be volatile but impurities should be non-volatile
4.It requires fractional columns for	4. It uses simple distillation set up with a Cleisen adapter.
