Polymorphism of triphenyl phosphite

摘要: The glass-forming liquid triphenyl phosphite (TPP) has recently attracted much attention due to the possible existence of a polyamorphism, i.e., two or more amorphous phases. In present work we provide experimental evidence polymorphism in TPP. addition already known conventional crystalline phase, which melts at 299.1 K, it been found that TPP can crystallize another polymorphic phase. new polymorph be obtained from phase direct cooling room temperature up 245 K where is held for 15 min and then heated 270 K. At crystallization occurs, 291.6
