Kinetics and vaporization of anil in nitrogen atmosphere – Non-isothermal condition

Abstract: 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 o… Show more

“…The apparent activation energy varied with increasing conversions and that shows volatiles degradation about a 50-85% (Manikandan et al, 2012). Thus, the DRP biomass presents two small values of activation energy in the range a 10 and 45% between 29.49 kJ/mol and 47.83 kJ/mol.…”

“…El análisis fotoacústico mostrados en la figura 9, revela dos hallazgos importantes, primero, existe un pico bien definido y una serie de picos en el intervalo de temperatura entre 200 y 400 °C, segundo, la descomposición del colorante inicia en 510 °C, estos resultados coinciden con los encontrados por las distintas investigaciones [6,56,61]. Con esto, se concluye que el primer pico bien definido se debe a la sublimación del índigo, mientras que la siguiente serie de picos son el resultado de la sublimación del dehydroindigo [62].…”
