20100317845 | Sucrose of new confrontational polymorphs and manufacturing method thereof - A sucrose of a conformational polymorph and its manufacturing method are disclosed. The sucrose is a Form II sucrose having a melting point of 140-180° C., and furfuryl alcohol is added into a saturated sucrose solution by a reverse solution method, such that the saturated solution is recrystallized to form a new sucrose. The sucrose of this conformational polymorph has a melting point lower than the melting point of a general Form I sucrose, and the solubility of the Form II sucrose is different from the solubility of the Form I sucrose. Thus the Form II sucrose can be used as an excipient of medicines, sacrificial fiber blood vessel network structure for cell cultivations, or the manufacture of an optical interference wavy device. Since the hydrogen bonds in the molecular structure of the Form II sucrose and the Form I sucrose are different, the mechanoluminescence of the sucrose is affected. | 12-16-2010 |
