Thermal Decomposition of the Acetone Cyclic Diperoxide in 1-octanol Solution
نویسندگان
چکیده
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/mol; ΔS = -19.1 ± 0.6 cal/mol K; Ea = 26.6 ± 0.3 kcal/mol), support a reaction mechanism which includes a homolytic rupture of one peroxidic L. C. A. Leiva et al 112 bond of the ACDP molecule with participation of the solvent and involving a biradical intermediate.

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...

Ionomers are generally described by copolymers having either acrylic or methacylic acid as one component and the other component is mostly either ethylene or styrene. The objective of this research was to study the thermal behaviour and stability of ionomers of styrene with some alkali metal acrylates. These materials have been synthesized by neutralization of the respective copoly...
