RDX Kinetic Model Evaluation by Nth Order Kinetic Algorithms and Model Simulations

Article Preview

Abstract:

A kinetic model based on the thermal decomposition of 1,3,5-trinitro-1,3,5-triazmane (RDX) was constructed via differential scanning calorimetry (DSC), well-known kinetic equations, curve-fitting analysis, and simulations of thermal analysis. Our objective was to analyze thermokinetic parameters derived from heating rates used in DSC and compare simulations of thermal decomposition under various kinetic models. Experimental results were strongly dependent on the validity of the kinetic model, which was based on an appropriate mathematical model and a proper method for the evaluation of kinetics. Through six types of kinetic algorithms, a reasonable value of the Ea of the thermal decomposition of RDX was obtained. Finally, this study established a novel green technology for the thermal analysis of reactions and obtained information on the characteristics of thermal decomposition and reaction hazards of RDX.
