A hierarchical set of kinetic models were proposed and discussed for simulation of autocatalytic decomposition of cumene hydroperoxide
(CHP) in cumene at low temperatures. The hierarchy leads from a formal model of full autocatalysis, which is based on conversion
degree as a state variable, through a two-stage autocatalytic concentration-based model to a meticulous multi-stage model
of the reaction. By the ForK (Formal Kinetics) and DesK (Descriptive Kinetics) software, developed by ChemInform Saint Petersburg
(CISP) Ltd., the related kinetic parameters and their significance have also been estimated and elucidated. Through this best-fit
approach, it is possible to formulate a systematic methodology on the kinetic studies for thermal decomposition of typical
organic peroxides with autocatalytic nature, specifically at low temperature ranges.
