Thermal Decomposition of the Acetone Cyclic Diperoxide in 1-octanol Solution

The thermal decomposition reaction of acetone cyclic diperoxide (ACDP) in 1-octanol (OCT) solution, at the temperatures and initial concentration ranges of 130° -166 oC and (0.94-3.00) x 10 mol/L , respectively, follows a pseudo-first order kinetic law. Acetone is the main organic decomposition product observed. The activation parameters values of the initial reaction step (ΔH = 25.8 ± 0.3 kcal...

Solvent Effect of Oxygen in the Thermolisys Decomposition of the Acetone Diperoxide

In this paper, the kinetics of the thermal decomposition reaction of 3,3,6,6-tetramethyl-1,2,4,5 tetroxane (ACDP) is investigated in various oxygen solvents at different temperatures. Linear relationships are observed between the enthalpy and entropy of activation of the unimolecular reactions of those diperoxides. The isokinetic temperature calculated by Leffler’s treatment is 527.2K, which is...

Thermal decomposition reaction of acetone triperoxide in toluene solution

The thermal decomposition reaction of acetone cyclic triperoxide (3,3,6,6,9,9-hexamethyl-1,2,4,5,7,8-hexaoxacyclononane, ACTP) in the temperature range of 130.0-166.0 degrees C and an initial concentration of 0.021 M has been studied in toluene solution. The thermolysis follows first-order kinetic laws up to at least ca. 78% acetone triperoxide conversion. Under the experimental conditions, a r...
