Polymorphism equilibrium melting data

X-ray data of dioctadecyldimethylammonium chloride (DODMAC) show a typical structure of dialkylammonium salts [4]. Thermal analysis of dry DODMAC crystals reveals a reversible solid crystalline-solid crystalline phase transition at 325 K i.e., two equilibrium polymorphic forms exist. Melting at —420 K is irreversible and is accompanied by chemical decomposition. [Pg.472]
