WebThe solubility of a compound in organic solvents or water is equally important for screen design and later for process development. For designing a screen, for instance around cooling crystallization, you need to select solvents that have sufficient solubility and that have a high dependency of solubility on temperature. WebThis temperature is called the “metastable limit”, and the difference between this temperature and the solubility curve is known as the metastable zone width (MSZW). By carefully controlling the level of …
