Abstract
Vaporization/sublimation enthalpies for twenty-one disubstituted benzenes were calculated from dissolution enthalpies and solvation enthalpies in four solvents of different polarity: carbon tetrachloride, benzene, N,N-dimethylformamide, and acetonitrile. The values of solvation enthalpy were calculated using group-additivity scheme for each solvent. Dissolution enthalpies of some substances were taken from literature and fifty-six original values were measured in the present work. The calculated values of vaporization/sublimation enthalpy were compared with the literature data. It was concluded that calculated vaporization/sublimation enthalpies do not depend on the choice of solvents excluding those that interact with the solute specifically.
