    Notizen: Abstract The thermal conductivity of new environmentally acceptable fluorocarbons HFC-134a (CH2FCF3), HFC-143a (CH3CF3), HCFC-141b (CH3CCl2F), and HCFC-142b (CH3CCl2F) in the gaseous phase has been measured in the temperature range 293–353 K at pressures up to 4 MPa. The thermal conductivity has been measured with a coaxial-cylinder cell on a relative basis. The apparatus was calibrated with He, Ne, Ar, Kr, N2, CH4, and SF6 as reference fluids. The uncertainty of the experimental data obtained is estimated to be within 2% except for the uncertainty associated with the reference thermal-conductivity values. The excess thermal conductivity has been correlated satisfactorily as a function of density.

    Isotope effect on the viscosity of benzene and cyclohexane mixtures under high pressures (1993)
    Springer
    International journal of thermophysics 14 (1993), S. 67-77

    Thema: Physik
    Notizen: Abstract Viscosities of binary mixtures of cyclohexane with protiobenzene, C6H6, or deuteriobenzene, C6D6, have been measured at 298 and 323 K and at pressures up to 50 MPa using a capillary viscometer. The viscosities of these mixtures obtained were represented by a empirical Tait-type equation within the experimental uncertainty of ±2%. The effect of the isotopic substitution on the viscosity has been discussed.
