An efficient reliable method to estimate the vaporization enthalpy of pure substances according to the normal boiling temperature and critical properties

The heat of vaporization of a pure substance at its normal boiling temperature is a very important property in many chemical processes. In this work, a new empirical method was developed to predict vaporization enthalpy of pure substances. This equation is a function of normal boiling temperature,...

In this work, a new empirical method was developed to predict vaporization enthalpy of pure substances. This equation is a function of normal boiling temperature, critical temperature, and critical pressure. The presented model is simple to use and provides an improvement over the existing equations for 452 pure substances in wide boiling range. The results showed that the proposed correlation is more accurate than the literature methods for pure substances in a wide boiling range (20.3–722 K). http://www.sciencedirect.com/science/article/pii/S2090123213000386EnthalpyVaporizationCorrelationPure substancesNormal boiling temperature
