摘　　要：用差热分析方法(DTA)、热重分析法(TG)和微分热重分析法(DTG)研究水溶性苯胺蓝在空气流中的热氧降解过程动力学,发现水溶性苯胺蓝热氧降解过程由三个步骤组成。用Coats-Redfern方程进行动力学处理,确定水溶性苯胺蓝热氧降解的表观反应级数为1.7、2.0、0.9和活化能为254.6、331.5、597.7kJ/mol。DTA, TG-DTG techniques were used to study thermal oxidation degradation process and kinetics of complex Aniline blue W. S in air. It has been found that thermal oxidation degradation process of complex Aniline blue W. Sconsists of three steps. Treated with Coats-Redfern equation, we found that the apparent degradation reaction orders were 1.7,2.0,0.9, and the activation energieswere 454. 6,331. 5,597. 7kJ/ mol of complex Aniline blue W. S.
