Excess molar enthalpies of mixing for sec- or tert-butyl chloride + benzene or toluene or o- or m- or pxylene have been determined experimentally as a function of mole fraction over the whole composition range at 308.15 K. were measured by a 2-drop calorimeter. The data have been analyzed qualitatively in terms of specific electron donor- acceptor type interactions and the interruption of the molecular order of the pure component in the mixture. The observed data of enthalpies of mixing for these binary mixtures are also analyzed in terms of Flory theory. The Flory theory gave poor agreement between experimental and calculated values.
