According to Ostwald's rule, usually less stable polymorphs crystallize before the stable form. The concept hinges on the idea that unstable polymorphs more closely resemble the state in solution, and thus are kinetically advantaged. The founding case of fibrous vs rhombic benzamide illustrates the case. Another example is provided by two polymorphs of titanium dioxide. Polymorphs have disparate stabilities. Some convert rapidly at room (or any) temperature. Most … WebHere we review the polymorphism of organic molecules, obtained through batch crystallization in solution carried out in a stirred vessel.
