the thermal decomposition reaction of trans-3,6-dimethyl-3,6-diphenyl-1,2,4,5-tetraoxacyclohexane (acetophenone cyclic diperoxide, dpaf), in different solvents (methanol, 1,4-dioxane, acetonitrile and 2-propanol/benzene mixtures) in the initial concentration and temperature ranges of (4.2-10.5) x 10-3 m and 140.0 to 185.0 oc, respectively, follows a pseudo first order kinetic law up to at least 70% dpaf conversion. an important solvent effect on the rate constant values, activation parameters (dh# and ds#) and reaction products obtained in different solvents is detected, showing that the reaction is accelerated in alcohols.
