Excess molar enthalpies of dibromomethane with acetonitrile, furan and acetophenone at 303.15 K
Excess molar enthalpies H-epsilon 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 H-epsilon values. The results indicate the existence of specific interactions between all these components. (C) 2010 Elsevier B.V. All rights reserved.
