Abstract
In this work a method for determination of sublimation and vaporization enthalpies of substituted phenols was developed. This method is a modification of solution calorimetry approach. Modification is based on the novel relations, which bind solution, vaporization and sublimation enthalpies at 298.15K and fusion enthalpy at the melting temperature. According to novel relations the equations for calculating sublimation and vaporization enthalpies at 298.15K were offered. Calculated values of sublimation and vaporization enthalpies of phenol derivatives containing alkyls, halogens, –OCH3, –NO2, –COCH3, –COOCH3 groups, and dihydroxybenzenes were compared with literature data (298.15K) obtained by conventional methods. In most of the cases divergence does not exceed 2–3%.
