An isothermal displacement calorimeter was constructed for the determination of excess enthalpies of mixing of endothermal liquid systems. The calorimeter was calibrated with cyclohexane-benzene and cyclohexane-hexane systems at 298.15 K. The precision and accuracy are <1%. The excess enthalpy of ethanol-benzene system was determine at 303.15 K.
