Densities, Speeds of Sound, and Viscosities of Mixtures of Oxolane with Chloroethanes and Chloroethenes

Data on density, speed of sound, and viscosity for mixtures of oxolane with 1,2-dichloroethane, 1,1,1-trichloroethane, 1,1,2,2-tetrachloroethane, trichloroethene, and tetrachloroethene at 303.15 K are reported. The results are used to derive isentropic compressibility (k<INF>s</INF>), deviations in isentropic compressibility (Δk<INF>s</INF>), and deviations in viscosity (Δln η). Values of Δk<INF>s</INF> are positive in mixtures of oxolane with 1,2-dichloroethane and tetrachloroethene and negative in the systems oxolane + 1,1,1-trichloroethane, + 1,1,2,2-tetrachloroethane, and + trichloroethene. All the systems exhibit positive deviation in viscosity. The results are interpreted in terms of electron−donor−acceptor interactions between unlike molecules.
