Kinetic and safety parameters analysis for 1,1,- di-(tert-butylperoxy)-3,3,5-trimethylcyclohexane in isothermal and non-isothermal conditions

Over the past 30 years, the field of thermal analysis of organic peroxides has become an important issue in Chemical engineering departments, safety departments, and in companies working with polymerisation, petrifaction process, and so on. This study was carried out using differential scanning calorimetry to evaluate the kinetic and safety parameters in isothermal and non-isothermal conditions, for instance, temperature of no return, self accelerating decomposition temperature, time to maximum rate, activation energy, frequency factor, reaction order, and reaction heat (¢H), in terms of the hazardous material of 1,1,-di-(tertbutylperoxy)- 3,3,5-trimethylcyclohexane (TMCH) 88 mass%. We demonstrated that TMCH 88 mass% must be well controlled in the manufacturing process due to the unstable structure of O-O, which releases a great quantity of heat, >1300 J/g under decomposition. Results could contribute to the relevant plants adopting TMCH 88 mass% in a process, in order to prevent a fire or explosion accident from happening.
