WebThere are five major steps in the recrystallization process: dissolving the solute in the solvent, performing a gravity filtration, if necessary, obtaining crystals of the solute, collecting the solute crystals by vacuum filtration, and, finally, drying the resulting crystals. Dissolving the solute in the solvent WebThe first step of recrystallization is to dissolve the product mixture in a minimal volume of heated solvent that still results in a saturated — but not supersaturated — solution. Then, the solution is cooled to room temperature, decreasing the solubility of both the desired compound and the impurity. As the solution cools, crystallization ...
