摘要
采用热重法、微分热重法和差热分析法研究药物盐酸曲普利啶在空气流中的热氧降解历程及动力学,从而发现该药物的热氧降解过程由5个紧连步骤组成.用Coats-Redfern方程进行动力学处理,确定盐酸曲普利啶热氧降解的表观反应级数均为1.1,反应活化能分别为66.5,113.7,116.2,153.8和180.6kJ/mol.
DTA,TG,DTG techniques were used to study the thermal oxidation degradation and kinetics of triprolidine hydrochloride(C 19 H 22 N 2·HCl·H 2O) in air.It has been found that the thermal oxidation degradation of medicine C 19 H 22 N 2·HCl·H 2O is of five steps.Treated with Coats Redfern equation,the apparent degradation reaction orders of medicine C 19 H 22 N 2·HCl·H 2O are 1 1,the reactive energies are 66.5,113.7,116.2, 153.8, 180.6 kJ/mol.
