Prediction of TMCH thermal hazard with various calorimetric tests by green thermal analysis technology

Abstract

1,1,‐Di‐(tert‐butylperoxy)‐3,3,5‐trimethylcyclohexane (TMCH), a liquid organic peroxide, has been widely used in the chemical industry as a polymerization initiator. The thermokinetic parameters of TMCH are investigated by three types of calorimetric tests (isothermal, nonisothermal, and adiabatic) to determine thermal decomposition properties of TMCH using differential scanning calorimetry (DSC) isothermal tests, DSC nonisothermal tests, and vent sizing package 2 adiabatic tests, respectively. Comparisons of three kinds of thermal analysis models were done for kinetics simulation, which can result in a beneficial kinetic model and parameters of thermal decomposition of TMCH. The use of green technology to replace the complex methods and energy consumption of the traditional self‐accelerating decomposition temperature tests are discussed. There are significant disadvantages with traditional thermal analysis methods in terms of a novel, swift, and green technology, which is the achieved object here for preventing pollution and reducing energy consumption. © 2012 American Institute of Chemical Engineers AIChE J,, 2012

“…Therefore, the activation energy E(a) can be evaluated by the temperature dependence of the isoconversional rate without assuming any form of the reaction model f(a) [9][10][11][12].…”

Storage Safety Control and Management of Solid Naval Energetic Materials by Thermokinetic and Hazard Simulation

“…The safety parameters of the heat effect for the storage duration condition of the ammunition depot of a cabin include parameters such as isothermal time to maximum rate (TMR iso ),time to conversion limit(TCL), and total energy release(TER) [14,17], and in addition, the thermal reactivity properties of solid highly exothermic naval materials. Simulations of kinetic model scan be complex multi-stage reactions that may consist of several independent, parallel, and consecutive stages [14,17]:…”

“…The chosen approach was to establish a procedure for heat effect assessment that includes thermal hazard parameters, such as the self-accelerating decomposition temperature (SADT), control temperature (CT), emergency temperature (ET), and the critical temperature (TCR) [14,17], for a cartridge containing highly exothermic solid materials.…”

Prediction of the self‐accelerating decomposition temperature of organic peroxides

“…The literature survey on SADT highlights some of the good attempt to predict the SADT applying the Semenov theory-based numeric methods and the new kinetic methods. 9,[11][12][13][14][15] Although the experimental and predicted SADTs have a good correlation between them for many organic peroxides, these methods also have many drawbacks described elsewhere. 16,17 Furthermore, the application domain of the employed theories is essentially limited, and many practical problems cannot be solved without applying comprehensive models that require the use of numerical calculations.…”
