Fractional distillation is a separation technique where where chemical compounds are separated by heating them to a temperature at which one or more fractions vaporizes based on their differences in their boiling points; whereas crystallization is a method of refining substances by separating them based on their differences in their solubility in certain solvents.This is achieved by mixing the compound with a solvent,heating it and cooling it gradually so that each of its constituent components forms crystals that can be removed from the solution.
