Fractional distillation is a type of distillation which involves the separation of miscible liquids. The process involves repeated distillations and condensations and the mixture is usually separated into component parts. The separation happens when the mixture is heated at a certain temperature where fractions of the mixture start to vaporize.

Coal Tar. Richard D. Phillips, in Encyclopedia of Toxicology (Second Edition), 2005 Uses. Coal tar is a viscous liquid mixture of hydrocarbon compounds, derived along with coke, from the destructive distillation of coal in coking ovens. Coal tar itself may be subjected to distillation, a process that separates groups of the components of coal tar from groups of others.
