WebApr 7, 2024 · The crystallization procedure is possible as most solids tend to become more soluble in solvents as their temperature is increased. 3.3A: Ideal Temperature Profile For the best crystallization, the compound should be very soluble in the hot solvent and minimally soluble (or insoluble) in the cold solvent. WebIf the compound is very soluble in the solvent at room temperature, then getting the compound to crystallize in pure form from solution is difficult. For example, water is an excellent solvent for the recrystallization of benzoic acid. At 10°C only 2.1 g of benzoic acid dissolves in 1 liter of water, while at 95 °C the solubility is 68 g/L.
