✦ Synopsis

The standard molar enthalpy of formation of B = CH3C(CH3)2OOC(CH3)2CH3(l): DfH°m(B,l) = -(380.8 2 2.0) kJ•mol -1 , and its standard molar enthalpy of vaporization: DvapH°m(B) = (39.3 2 1.0) kJ•mol -1 have been determined at the temperature 298.15 K using combustion calorimetry, ebulliometry, and heat-capacity measurements by d.s.c. The obtained values were used to re-evaluate the standard molar enthalpy of formation of CH3C(CH3)2O .

as -(91.3 2 1.5) kJ•mol -1 .
