<span>Recrystallization
is another method of purification of solids in which an impure solid is
crystallize repeatedly to obtain amore pure solid and a larger one. Ethanol is
better suited as solvent in recrystallization of benzene than acetone because
it becomes soluble with benzene at a higher temperature. Ethanol is non polar

their polarity, especially in heating both benzyl and the solvent can lead to
more impurities that cannot be removed.</span>
