喹诺酮类(吡哌酸、诺氟沙星)药物的热分解特性研究
Studies on the thermal decomposition characteristics of Quinolone drugs of Pipemidic Acid and Norfloxacin
【摘要】 分别采用差示扫描量热法(DSC)、热重法(TG)和微分热重法(DTG),研究了喹诺酮类(吡哌酸、诺氟沙星)抗菌药的热分解动力学过程,计算了其热分解动力学参数——活化能(E),分析了其热分解机理,并剖析了喹诺酮类药物有机结构上的差异。
【Abstract】 The thermal characteristics of Quinolone drugs of Pipemidic Acid and Norfloxacin were analyzed by DSC (differentia scanning calorimetry),TG (thermogravimetry),DTG (differential thermogravimetry).The thermal kinetic parameter-energy of activation (E) was calculated as well.The thermal decomposition characteristics and the difference of Quinolone drugs in organic structure were analyed as well.
