Excess molar volumes, V-m(E), relative permittivities, epsilon(r), and refractive indexes, n(D), have been measured for binary mixtures of 1,1,2,2-tetrachloroethane (CHCl2CHCl2) with pyridine (C5H5N), anisole (C6H5OCH3), methyl ethyl ketone (CH3COC2H5), and 1,4-dioxane (1,4-C4H8O2) at 303.15 K. V-m(E) has been found to be negative throughout the entire mole fraction range for all these mixtures. The values of the deviations of epsilon(r) and n(D) from a mole fraction average, which are represented respectively by Delta epsilon(r) and Delta n(D) have been calculated. The results of V-m(E), Delta n(D), and Delta epsilon(r) for the various mixtures have been fitted by the method of least squares to smoothing equations.
