Static permittivity ([Formula: see text]), refractive index ([Formula: see text]) and density ([Formula: see text]) of binary mixtures of ethylene glycol mono phenyl ether (EGMPE) with 1-butanol (1-BuOH) over the entire range of mole fraction and at temperatures ([Formula: see text], 313.15 and 323.15[Formula: see text]K) have been measured. From the experimental data, parameters such as excess static permittivity ([Formula: see text]), excess permittivity at optical frequency ([Formula: see text]), effective Kirkwood correlation factor ([Formula: see text]), corrective Kirkwood correlation factor ([Formula: see text]) and Bruggeman factor ([Formula: see text]) have been calculated to obtain qualitative and quantitative information about the complex formation through H-bond in binary system. In order to predict the static permittivity of polar–polar binary mixtures six mixing rules were applied and for refractive index five mixing rule were applied. Experimental results of permittivity ([Formula: see text]) and refractive index (n) are compared with those obtained from theoretical calculations. Excess parameters were fitted to the Redlich–Kister type polynomial equation.

Thermal Conductivities

Recent experimental measurements of the thermal conductivity of mixtures of nitrogen and hydrogen are compared with values calculated from Hirschfelder’s theory of the transport of heat in mixtures of polyatomic gases. The discrepancies between theory and observation, though small, appear to be greater than the experimental error; the observed thermal conductivities almost always exceed the theoretical values. Similar small discrepancies have been reported in some other experimental work. It is shown that for mixtures of nitrogen and hydrogen the discrepancies are unlikely to be due to a failure to assign correct values to the parameters appearing in the theroretical equations. Attention is therefore drawn to the validity of the assumptions underlying the theory. Hirschfelder’s theory distinguishes translational and internal contributions to the conductivity of the mixture. It rests on the assumption, originally due to Eucken, that the translational contributions to the thermal conductivity of the individual constituents may be calculated as if the gases were monatomic, i.e. by setting K trans. = 2·5 nc v trans. .It is suggested that this is an overestimate of the translational contribution and that complete accuracy is therefore not to be expected from calculations based on Hirschfelder’s theory. A recent theoretical study by Mason & Monchick is in accord with this suggestion.
