Annotation of standard text ASTM E2071-00(2015) :

This practice describes the calculation of the heat of vaporization of a liquid or the heat of sublimation of a solid from measured vapor pressure data. It is applicable to pure liquids, azeotropes, pure solids, and homogenous solid solutions over the temperature range for which the vapor pressure equation fitted to the measured data is applicable. Vapor pressure data shall be measured in accordance to the test methods and shall be correlated with the Antoine equation. The heat of vaporization or sublimation is computed at the desired temperature from the vapor-pressure temperature derivative from the fitted Antoine equation by use of the Clapeyron equation.


Keywords:
Antoine equation, Clausius-Clapeyron equation, enthalpy of sublimation, enthalpy of vaporization, Haggenmacher equation, heat of sublimation, heat of vaporization, vapor pressure,, ICS Number Code 27.040 (Gas and steam turbines. Steam engines)
