Excess molar enthalpies of dibromomethane with acetonitrile, furan and acetophenone at 303.15 K

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 image and image have also been evaluated with the help of HE values. The results indicate the existence of specific interactions between all these components.
