Abstract

The standard enthalpies of combustion of diphenyl oxalate and benzoic anhydride have been measured by static combustion calorimetry. The results have been used to derive the standard enthalpies of formation: ΔHf°(diphenyl oxlate, c)=–129·0 ± 0·8 and ΔHf°(benzoic anhydride, c)=–99·3 ± 0·4 kcal mol–1. The thermochemistry of these and related oxygenated compounds is discussed. Values for bond dissociation energies have been derived and are discussed in the context of possible decomposition pathways.
