PROCESS FOR PREPARING A CRYSTAL SUSPENSION |
摘要 |
<p>A process for preparing a crystal suspension of an organic compound which has a DELTAH/RT value (where DELTAH is the heat of fusion of the compound, R is the molar gas constant and T is the melting point of the compound) in the range of 1 to 10, the process comprising dispersing a melt of the organic compound in a liquid dispersion medium, typically water, to form an emulsion, typically an oil-in-water emulsion, cooling the emulsion below the melting point of the organic compound and subjecting the emulsion to ultrasonic vibration.</p> |
