  Abstract:  

The activation energy of the linear non-isothermal evaporation of 4-[(4-chlorobenzyl)oxy]-4’-trifluoromethyl-azobenzene has been determined by various linear integral isoconversional methods. Activation energy may be evaluated using several isoconversional methods as the well-known Tang et al. method, Generalized KAS method, but also by means of two so-called “local linear integral” (Tang & Chen) and ”average linear integral” (Ortega) isoconversional methods. A comparison study has been carried out in order to understand how the activation energy values are affected when using different approaches.

 

Keywords: azomonoether dyes, non-isothermal kinetics, linear integral, local linear integral and average linear integral isoconversional methods.
