EXCESS MOLAR ENTHALPIES OF (A HETEROCYCLE + BENZENE OR CYCLOHEXANE)

The excess molar enthalpies of (pyrrole or furan or thiophene + benzene or cyclohexane) and (thiazole + benzene) at 298.15 K and of (1,2-dimethylimidazole + benzene) at 308.15 K, measured with a quasi-isothermal calorimeter at atmospheric pressure and in the absence of vapour phase, are reported. The experimental results have shown that excess enthalpies are positive over the entire composition range, and higher for cyclohexane than for benzene. © 1990.
