Vacuum crystallization

Vacuum crystallization is a process used to purify and solidify substances, often chemicals or pharmaceuticals. It involves dissolving a compound in a solvent and then reducing the pressure (creating a vacuum), which lowers the boiling point of the solvent. As the solvent evaporates under vacuum, the dissolved substance becomes more concentrated and begins to crystallize or solidify. This method allows for crystallization at lower temperatures, minimizing decomposition or damage to sensitive materials. The resulting crystals are usually pure and suitable for further use or analysis.
