A fraction in chemistry is: a quantity collected from a batch of a substance in a fractionating separation process. In such a process, "a mixture is separated into fractions," which have compositions that vary according to a gradient. A fraction can be defined as a group of chemicals that have similar boiling points. A common fractionating process is fractional distillation, in which separation is achieved by condensing vapor over a range of temperatures. It is used to produce liquor and various hydrocarbon fuels, such as gasoline, kerosene and diesel.
A fraction is the: product of a fractionating column, a vast chamber designed to separate different substances (such as crude oil) based on their boiling point.
Fraction could also refer to a description of the——composition of a mixture, e.g. mass fraction/mole fraction.
For a simpler definition a fraction is a part of the fractionating column where a compound with one boiling point can be separated from other compounds with different boiling points.
