Crystallization point
WebAug 11, 2024 · An ideal crystallization solvent should be unreactive, inexpensive, and have low toxicity. It is also important that the solvent have a relatively low boiling point (b.p. often \(< 100^\text{o} \text{C}\) as it's best if the solvent readily evaporates from the solid once recovered. Table 3.1 shows a list of common solvents used with ...
