چکیده
|
The thermal vaporization kinetics of schiff’s base was studied by thermogravimetry (tg) and differential thermal analysis (dta) techniques using non-isothermal conditions. the kinetic parameters were calculated under model-free (friedman’s, kissinger–akahira–sunose (kas) and flynn–wall–ozawa (fwo) methods) and model-fitting (coats–redfern, cr) methods. the results of the friedman’s isoconversional analysis of the tg data suggest that the investigated vaporization process follows a single-step reaction. based on the obtained results, the mass loss is caused mainly by vaporizations and not by decomposition. the most probable kinetic model for vaporization of the compound is p2 (power law).
