Solvent selection for recrystallization is a critical step in the purification of organic compounds. The solvent must be able to dissolve the impure compound at elevated temperatures and then allow the compound to crystallize upon cooling. The choice of solvent is also important for the efficiency of the recrystallization process and the quality of the crystals obtained.
The ideal solvent for recrystallization will have the following properties:
Solvent selection for recrystallization is a critical step in the purification of solid compounds. The ideal solvent should dissolve the impurities but not the desired product, allowing for selective crystallization of the target compound. Several factors must be considered when choosing a solvent for recrystallization, including the solubility of the compound, the selectivity of the solvent, and the physical properties of the solvent.
The solubility of the compound in the solvent is the most important factor to consider. The solvent should dissolve the impurities but not the desired product. If the solvent dissolves both the impurities and the product, then recrystallization will not be effective. The selectivity of the solvent is also important. The solvent should selectively dissolve the impurities but not the product. If the solvent dissolves both the impurities and the product, then the recrystallization will not be effective.
