Distillation:
Distillation is a method used to isolate boiling point liquids and consists of gaps of at least 50 degrees.
You don't have to replicate the cycle to get pure components.
The set-up is simple and creative. Want a basic two-flask device and a condenser.
Use this method to distinguish a solvent from a solute.
Used for seawater purification.

Fractional distillation:
Fractional distillation is a method used to isolate liquids which boil closer.
In order to produce pure components the process must be replicated many times.
The testing system is complicated. We need a robust column-fractionation apparatus.
Cannot use this method to distinguish a liquid from a liquid.
Used when refining crude oil.
