ABSTRACT

The heat capacity of ethyl decanoate in the interval of (5 to 370) K was measured in an adiabatic calorimeter. The triple-point temperature Tfus = (253.60 +- 0.02) K and the enthalpy of fusion ?crliqHmdeg = (32.29 +- 0.04) kJ*mol-1 were determined. The vapor pressure over liquid ethyl decanoate in the interval of (294 to 323) K was measured by the Knudsen method. The calorimetric enthalpy of vaporization ?liqgHmdeg (304.8K) = (69.9 +- 0.7) kJ*mol-1 was determined in an MID-200 Calvet-type microcalorimeter. The standard enthalpy of formation for liquid ethyl decanoate at 298.15 K ?fHmdeg (liq) = (-682.7 +- 2.4) kJ*mol-1 was determined in a static bomb combustion calorimeter. From these data, the standard enthalpy of formation for gaseous ethyl decanoate was evaluated to be ?fHmdeg (g) = (-612.2 +- 2.4) kJ*mol-1. The formation enthalpy was also calculated using quantum chemical methods via homodesmic reactions at different theory levels. The results are in excellent agreement with the experimental value.
