Estimation of preexponential factor from thermal decomposition curve of an unweighed sample

Heat Transfer Analysis and Assessment of Kinetics Systems for PBX 9501

“…Further research published by Zinn and Rogers in 1962 [4] correlated geometric effects and investigated material composition changes. In order to interpret the experimental data, the theoretical model used Rogers continued his research into high explosive analysis, and in 1967, Rogers and Smith authored an article [5] that introduced a simple method of estimating the pre-exponential factor used to solve the first-order decomposition in the reactant. Realizing the difficulties in measuring the decomposition energies of reactions involving gaseous products, Rogers published a paper in 1972 [6] on a method of simplifying the determination of the rate constants.…”

Evaluation of Linear Kinetic Methods From Pyrolysis Data of Spanish Oil Shales and Coals

“…Although linear methods to derive the kinetic analysis from TG data were developed many years ago [5,7,[11][12][13][14], they are extensively used nowadays in studying kinetic analysis of polymers decomposition [15][16][17][18][19][20][21]. Despite their popularity, there are cast doubts on the accuracy of the approximations on which the linear methods are based because they provide significant deviations in the determination of kinetic parameters.…”

Synthesis of new polyimides with 1,2,3-triazole units

“…The DSC scans of AB-monomers 3(a-d) and equimolecular mixtures of monomers 5(a-c) with PBPA are presented in Figure 2a and 2b, respectively. The DSC data are listed in Table 1 Activation energy using the method proposed by Rogers et al [13][14].…”

“…T onset and T f varied between 85-103 °C and 180-195 °C, respectively. The activation energy (E a ) values, calculated by Rogers's method [13][14], are in the range 30.31-117.54 kJ/mol.…”
