Vapour pressures and enthalpy of vaporization of L-alkanols in terms of associated mixtures models.

Abstract

This article presents a correlation of vapour pressures of l-alkanols when the term describing a chemical contribution is included into the integrated form of the Clapeyron equation. The enthalpy and the entropy of hydrogen bond formation were determined independently from l-alkanol-n-alkane mixtures properties. Prediction of vapour pressures of l-alkanols using a concept of the homomorph is discussed.
