Solution and solvation enthalpies of aromatic derivitives in binary mixtures. Dipole moment and dielectric properties

Abstract

© 2019 Elsevier B.V. In the present work a thermochemistry of solution and solvation of mono- and di-substituted chloro- and nitrobenzenes in binary mixtures was studied. The infinite dilution solution enthalpies of 1,2-dichlorobenzene,1,4-dichlorobenzene, 1,2- dinitrobenzene, 1,4-dinitrobenzene, 1-chloro-2-nitrobenzene and 1-chloro-4-nitrobenzene in binary mixtures of benzene-cyclohexane, benzene-acetonitrile, carbon tetrachloride-acetonitrile at different molar ratios (0, 0.25, 0.50, 0.75, 1.00) solvents were measured at 298.15 K. Based on experimental data the solvation enthalpies in binary mixture were calculated. It was shown that the solvation enthalpies slightly depend on neither the location of chloro- and nitro - substituents in aromatic ring nor a composition of binary mixture.
