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

open access: yesJournal of Advanced Research, 2014
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.
