Excess volumes and speeds of sound of mixtures of 1,2-dibromoethane with chlorinated ethanes and ethenes at 303.15Â K

Excess volumes VE, speeds of sound u and isentropic compressibilities Ks at 303.15 K are reported for five binary mixtures containing 1,2-dibromoethane as common component and 1,2-dichloroethane, 1,1,1-trichloroethane, 1,1,2,2-tetrachloroethane, trichloroethene and tetrachlorothene as non-common component. The excess volume data suggests that increase in the number of chlorine atoms on ethane decreases VE, while when on ethene increases the VE. Further, the data suggest that the molecular interactions are stronger in + chlorinated ethanes than in + chlorinated ethenes.
