Question

why is fractional distillation used? ​

Answer 1

For example, fractional distillation is used in oil refineries to separate crude oil into useful substances (or fractions)

having different hydrocarbons of different boiling points. The crude oil fractions with higher boiling points: have more

carbon atoms.

Answer 2

Answer:

Fractional distillation means separation of liquid mixture into fraction differing in boiling point (and hence chemical composition) by means of distillation typically using fractionating column
