摘要: 用热天平研究了中间体及染料的非等温脱羧反应动力学,用Avrami-Erofeev成核和生长模型关联出反应动力学方程,并算出动力学参数。

Abstract: The kinetics of decarboxylation of intermediates and dyes containing carboxymethylsulfonyl group was studied by thermogravlmetry. The temperatures of decarboxylation of initial,final,Tmax and intensive decomposition were obtained through experiment. The Avrami-Erofeev equation of n=1,which is the same formation as the first order chemical reaction, was used to describe the decarboxylation process. The apparent kinetic parameters were obtained.There is compensating effect between activation energy and frequency factor for these different intermediates and dyes.
