Difference between distillation and fraction distillation?
Answer
Distillation |
Fraction distillation |
Simple distillation is used to separate liquids with boiling point gaps of at least 50 degrees. |
Fractional distillation is used to separate liquids with closer boiling points. |
Uses a simple apparatus with 2 flasks and a condenser. |
Uses a complex apparatus with a fractionating column. |
In distillation, the process does not have to be repeated. |
Here, the process has to be repeated several times to get the pure components. |
Can be used to separate the solvent from a solute. |
Cannot be used to separate a solvent from a solute. |
Application: Used to purify sea water. |
Application: Used in crude oil refining. |
Distillation vs Fractional distillation
(In fractional distillation, a fractional column is used)
