ENTHALPY OF VAPORIZATION The molar enthalpy (heat) of vaporization ∆vap H, H, which which is defined as the enthalpy change in the conversion of one mole of liquid to gas at c onstant temperature, is tabulated here for approximately 850 inorganic and organic compounds. Values are given, when available, both at the normal boiling point t b, referred to a pressure of 101.325 kPa (760 mmHg), and at 25 °C. Substances are listed by molecular formula in the modified Hill order (see Preface). The values in this table were measured either by calorimetric techniques or by application of the Claperyon equation to the variation of vapor pressure with temperature. See Reference 1 for a discussion of the accuracy of different experimental techniques and for methods of estimating enthalpy of vaporization at other temperatures.
