Fraction (chemistry)
Lua error in package.lua at line 80: module 'strict' not found. A fraction in chemistry is a quantity collected from a sample or 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. 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 based on their boiling point, e.g. crude oil.
Fraction could also refer to a description of the composition of a mixture, e.g. mass fraction or 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.
