Question

what is the difference between simple distillation and fractional distillation ​

Answer 1

Answer:

Explanation:

The main difference between fractional distillation and simple distillation is that simple distillation separate liquids with boiling point gaps of at least 50 degrees whereas fractional distillation separates liquids with closer boiling points.

Answer 2

Answer:

Explanation:

Simple distillation

Simple distillation is used when the boiling points of chemicals in a mixture having large differences (more than 25°C).

No fractionating columns used as the difference in the boiling point of mixture is large.

E.g. Process used in separating kerosene and petrol

Fractional distillation

Fractional distillation is used when the boiling points of chemicals in a mixture are close to each-other, usually within 77°F (25°C).

Fractionating columns used  to separate the mixtures.

E.g. Process used in the separation of Crude Oil into useful fractions
