Decomposition Kinetics of 1,1-Dihydroperoxycyclohexane in Some Organic Solvents

Background: 1,1-Bishydroperoxides are used as oxidizing agents, radical initiators, in addition, studies of biological activity show the promise of this area of research. Objective: There are currently no kinetic data on the thermal stability of these peroxides in various solvents. Therefore, we investigated the thermal stability of 1,1-dihydroperoxycyclohexane as the most widely used at present. Methods: The rate constants and activation parameters were measured at the temperature range of 100- 170°C in the presence of 2-naphthol, which inhibits the induced decomposition of the peroxide by free radicals. Peroxide concentration was determined by iodometric method. Results: The rate constants of the reaction with the solvents and of the monomolecular decomposition of the peroxide were determined. Conclusion: The use of DHPC as a radical initiator requires taking into account its reactions with the solvent and/or monomer, in addition to its monomolecular decomposition with the formation of free radicals.
