“…Therefore, to solve this problem, in this study the kinetic parameters were calculated by the isoconversional method based on the calculation of activation energy and the product term at different degrees of conversion, a, without assuming the form of the reaction model, f(a). The kinetic analysis by the isoconversional method was performed using the AKTS Thermokinetics software package [22][23][24][25][26].…”

The rapid evaluation of the hazard of heat generation by oxidation of materials using a differentialtype adiabatic calorimeter (DAC) was investigated, assessing oleic acid and polyethylene glycol samples of various masses. The same samples were analyzed using an accelerating rate calorimeter and a high-sensitivity calorimeter (C80), for comparison purposes. The kinetic parameters of the exothermic reactions were determined from the C80 data, and the associated exothermic behaviors of the samples were compared with those observed using the DAC. Oleic acid exhibited self-heating at lower temperatures compared with polyethylene glycol according to each measurement method. Thus, the comparative risk of heat generation of chemical materials by oxidation may be evaluated using a DAC. The DAC technique allows the prediction of exothermic behavior based on a single measurement performed over the course of a single day. Thus, the assessment of autoxidation exothermic behaviors using a DAC may be applied to allow rapid screening of the hazard of heat generation induced by oxidation of chemical substances.

The minimum number of thermoanalytical experiments that should be considered with the aim of performing a complete and reliable kinetic analysis when using semiempirical models is the problem of concern. It is shown by means of a series of numerical experiments that three differential scanning calorimetric (DSC) dynamic runs performed at different heating rates provide a complete and reliable kinetic analysis while the topological structure of two DSC curves is enough to determine the semiempirical model (among reaction order and Sestack–Bergrenn) that better describe the experimental data. The procedure is analyzed by means of the simulation of a complex kinetic scheme and the results verified considering the thermal decomposition of cumene hydroperoxide. The proposed approach can be easily generalized to different kinetic models and is provided with a possible criterion devoted to identify autocatalytic processes by means of dynamical DSC experiments. © 2011 American Institute of Chemical Engineers AIChE J, 58: 1869–1879, 2012
