The solubility is the most important and basic parameter in crystallization process. The supersaturation, the function of the solubility, is a fundamental driving force for precipitating crystals in solution. In the study, the solubility of β and ε form of HNIW was measured. In various solvents such as ACT, EA, DMSO and ACN, solubility of each forms was measured as function of temperature. Also, for the drowning out crystallization, the solubilities were measured as function of fraction of mixture solvent. The solvent of mixture solvent is same as above, the anti-solvent is iso propyl alcohol. The experimental method has two type. The one is a method that solution was collected by using filter and evaporated and then weighed the residue. Another is a case of weak volatile solvent. In this case, the FBRM and PVM were used by measuring the solubility. |
