Abstract
1,1-Bis(tert-butylperoxy)-3,3,5 trimethylcyclohexane (TMCH), a typical organic peroxide, is normally an initiator agent and cross-linking agent of styrene and polyethylene. Metal ions, used as catalysis substances, can affect the thermal stability of TMCH. However, they are commonly found everywhere in processing areas such as in rusty rotating equipment, metal containers, and aging pipelines. Thus, we investigated the thermal stability of TMCH mixed with metal ions and acquired thermokinetic parameters using calorimetric data. Through isoconversional kinetic analysis simulations, thermokinetic parameters were obtained under isothermal conditions using nonisothermal experimental data. In DSC experiments, the E a of TMCH mixed with CuCl2 was lower than that of pure TMCH. TMR iso of pure TMCH was shorter than that of TMCH mixed with CuCl2 in isothermal experiments. The results of the simulations and experiments were compared and discovered to be similar. The results can be a reference for TMCH mixing with metal ions during its storage and transportation.
