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
