Abstract
The data on enthalpies of formation (Δf H ○) of alkylcarbonyl radicals are expanded to 22 items. The reference value of Δf H ○ for diacetylperoxide in the gas phase (−485.5 kJ/mol) is determined via recalculation from evaporation enthalpy (n-C5H11C(O)O)2. The Δf H ○ values of 22 diacylperoxides (gaseous) are calculated and used in combination with the literature data on dissociation energies of D(O-O) bonds in them to determine the Δf H ○ of corresponding radicals. The interrelation between structure and properties (the enthalpy of formation) is considered, and the parameters for the calculated prediction of Δf H ○ are found.
