By using Gray''s relaxation theory of transport processes for monatomic liquids35 and the two-parameter (ε
*, γ
*) corresponding states approximation, correlations for thermal conductivity and shear viscosity of halocarbon liquids and their mixtures have been developed. In order to make the relaxation concept useful, the relaxation time was assumed to be a simple function of the thermal speed, u = (3 kT/m)
1/2, and the distance variable γ.
Since the theory of intermolecular potential has not yet been established for halocarbons, the directly measurable properties of liquid volume, V
B, and temperature, the normal boiling point, T
B, were sleeted as the set of reducing constants.
In spite of these simplifications, the average deviation of the correlated thermal conductivity of eleven halocarbons and two mixtures is within ±3% ; ''and the shear viscosity of five pure halocarbons and three mixtures is within ±5%.
