3,6-diphenyl-1,2,4,5-tetraoxane(DFT) has been prepared in order to study the effect of temperature on the reaction kinetics in
methylcellosolve solution. The thermolysis reaction fulfills a kinetic law of the first order up to conversions approximately 60 % of the
DFT. The values of ΔH#=20.2±1.0 kcal mol-1 and ΔS#= -25.3±1.4 cal mol-1 K-1 of the rupture of one O-O bond in the diperoxide molecule
were obtained by measuring the remanent diperoxide at different reaction times by GC technique. Benzaldehyde and benzoic acid were
detected by GC as the major organics products of the reaction.
Keywords: Cyclic diperoxide, diphenyl diperoxide, tetroxane, thermolysis.
