1. Recrystallization
Important method of purification for solid organic compounds.
The substance to be purified is dissolved in a heated solvent.
The saturated solution is allowed to cool and a regular array of crystals will begin to form, leaving any impurities in solution.
The crystals are rinsed with cold solvent to remove any adhering impurities.
The crystals are then dried.
