Definition: A process used to purify crude chemical compounds containing solid impurities. A solvent is chosen in which the desired product is insoluble and the undesired by-products are very soluble (or vice versa). The crude material is washed with the solvent and filtered away, leaving the purified product in solid form and any impurities in solution.
