enthalpy of vaporizationfar-infrared spectroscopyionic liquidsThe determination of enthalpies of vaporization for ionic liquids is a real challenge. R. Ludwig et al. show on p. 1623 that this important thermodynamic property can be estimated from low vibrational bands in the far infrared spectra of ...
An additive method for predicting the standards heats of formation at 298 K of aliphatic and alicyclic polynitro-compounds is described. It consists in three steps (i) the evaluation of the enthalpy of formation in the gaseous state (ii) the estimation of the enthalpy of vaporization for a ...
This article discusses methods for prediction of normal boiling point, normal melting point, critical pressure, critical temperature, critical volume, standard enthalpy of vaporization at 298 K, standard Gibbs energy, and standard enthalpy of formation at 298 K. The predictions are based exclusively ...

A multiple linear regression model predicts K-ma as a function of chemical's K-oa, enthalpy of vaporization ( increment H-v), temperature, and material type. The model shows good fitting of the experimental dataset with adjusted R-2 of 0.93 and has been verified by internal and external ...
A general technique for the estimation of sublimation enthalpies is described and applied to hydrocarbons. The vaporization enthalpy of a hydrocarbon is obtained by using a simple relationship based on the type and number of carbons present. Fusion enthalpies are estimated using a group additivity ...
