Abstract
Abstract Excess molar enthalpies HE at 303.15 K using a microcalorimeter have been determined for binary liquid mixtures of dibromomethane (DBM) with acetonitrile, furan and acetophenone over the entire composition range. The excess molar enthalpies values are endothermic for DBM + acetonitrile, and +furan but they are exothermic for the system DBM + acetophenone. The observed values are fitted with the Redlich–Kister equation by means of the least squares method. The excess partial molar enthalpies of the components H m , 1 E and H m , 2 E have also been evaluated with the help of HE values. The results indicate the existence of specific interactions between all these components.
