Vaporization enthalpies of self-associated aromatic compounds at 298.15 K: A review of existing data and the features of heat capacity correction. Part I. Phenols

Abstract

Vaporization, sublimation and fusion enthalpies of 39 phenol derivatives were thoroughly analyzed using Kirchhoff's and Hess's laws of Thermochemistry to derive the reliable ΔlgH°(298.15 K) values. During the analysis, the correction for non-ideality for the high-temperature vaporization enthalpies was performed. The crystal, liquid and gas heat capacities available from the literature were complemented with the additional experimental measurements of the condensed phases and the computations of the ideal gas properties. Analyzing the available information, we proposed a simple approach for the estimation of the temperature dependence of the vaporization enthalpy of phenol derivatives that showed high accuracy for compounds of various structure.
