Fractional distillation is useful for separating a mixture of substances with minor differences in boiling points. The minor difference means the gap between the boiling points should be less than 25 Kelvin.
It is used for the distillation of crude oil in the petroleum industry thereby resulting in the manufacturing of gasoline, lubricating oil, diesel, and plastics.
