For many compounds, the solubility increases with temperature.

Crystallization - Wikipedia

WebAntisolvent crystallization is a process in which the drug product can be obtained from aqueous solutions by the addition of nonsolvent compounds (antisolvent), which results in a reduction of solute solubility. An ideal antisolvent should be completely miscible in the mother liquid but is insoluble for the solute drug material. WebMay 22, 2024 · Solubility Abstract The striking ability of impurities to significantly influence crystallization processes is a topic of paramount interest in the pharmaceutical industry. Despite being present in small quantities, impurities tend to considerably change a crystallization process as well as the final crystalline product. philly gov job

The crystallization process consists of two major events, nucleation and crystal growth which are driven by thermodynamic properties as well as chemical properties. Nucleation is the step where the solute molecules or atoms dispersed in the solvent start to gather into clusters, on the microscopic scale (elevating solute concentration in a small region), that become stable under the current operating conditions. These stable clusters constitute the nuclei. Therefore, the clusters …
