Molecular interactions in binary liquid mixures of dimethylsulphoxide with chloroethanes and chloroethenes

Abstract

Excess volumes (<i style="">V</i>^E) were measured over the entire mole fraction range for mixtures of dimethylsulphoxide with 1,2-dichloroethane, 1,1,1-trichloroethane, 1,1,2,2-tetrachloro-ethane, trichloroethene and tetrachloroethene at 303.15 K. The values of <i style="">V</i>^E are negative for the system dimethylsulphoxide +1,1,1-trichloroethane and positive for the systems dimethylsulphoxide + 1,2-dichloroethane, +1,1,2,2-tetrachloroethane, +trichloroethene, and tetrachloroethene. The experimental data have been interpreted on the basis of molecular interactions between unlike molecules.<b style=""></b>
