Solvent Effect in the Thermal Decomposition Reaction of trans-3,3-Dimethyl-5,6-tetramethylene-1,2,4-trioxacyclohexane

The kinetic data of the thermal decomposition reaction of trans -3,3-dimethyl-5,6-tetramethylene-1,2,4-trioxacyclohexane has been measured in different solvents (benzene, toluene, 2-propanol, 2-methoxyethanol, and p -dioxane) at 0.02 mol kg - 1 initial concentration and in the temperature range of 135.0−165.0 °C. The enthalpy and entropy of activation of the unimolecular reaction of this trioxane in several organic solvents have been correlated through “isokinetic relationships” to validate the existence of a genuine solvent effect on that reaction.
