Molecular Thermal Decomposition Mechanism and Kinetics of Ulipristal Acetate Pseudo-polymorph
摘要
Abstract
Ulipristal acetate pseudo-polymorph was prepared by cooling crystallization in ethanol.According to TG data,the thermal decomposition of ulipristal acetate pseudo-polymorph included two processes which were desolvation and molecular thermal decomposition as the temperature increased. Non-isothermal thermogravimetry was applied to study the thermal decomposition mechanism and thermal decomposition kinetics of molecular thermal decomposition of ulipristal acetate pseudo-polymorph. Based on different kinetic functions of corresponding molecular thermal decomposition mechanisms and the experimental data of ulipristal acetate pseudo-polymorph,the decomposition mechanism of molecular thermal decompo-sition process was analyzed and estimated,and the corresponding kinetic equation was also obtained.关键词
