ABSTRACT
The excess molar enthalpies, Hm E , of (N-methylformamide or N-methylacetamide + benzene, or + toluene, p-xylene, or mesitylene) at 303.15 K have been determined experimentally as a function of mole fraction. Hm E shows partial miscibility for the system N-methylformamide + p-xylene. Hm E is positive for all the mixtures.
