EXCESS VOLUMES, SPEEDS OF SOUND, AND ISENTROPIC COMPRESSIBILITIES OF 2-PROPYN-1-OL PLUS 1,2-DICHLOROETHANE, PLUS 1,1,1-TRICHLOROETHANE, PLUS 1,1,2,2-TETRACHLOROETHANE, AND PLUS TRICHLOROETHYLENE AT 303.15-K

Excess volumes and speeds of sound for the binary systems 2-propyn-1-o l + 1,2-dichloroethane, + 1,1,1-trichloroethane, + 1,1,2,2-tetrachloro ethane, and + trichloroethylene have been measured at 303.15 K. The da ta were used to calculate isentropic compressibilities. The excess vol umes for all the mixtures were found to be positive. The positive exce ss volumes and positive deviation in isentropic compressibilities have been attributed to the dissociation of self-associated alcohols with chloroalkanes or chloroalkene.
