The viscosity in binary liquid mixtures of water with ethylene glycol dimethyl ether (1,2-dimethoxyethane), diethylene glycol dimethyl ether (bis(2-methoxyethyl) ether), triethylene glycol dimethyl ether (1,2-bis(2-methoxyethoxy)ethane), and tetraethylene glycol dimethyl ether (2,5,8,11,14-pentaoxapentadecane), have been determined at 298.15 K over the whole range of mixture compositions. The viscosity data have been analyzed by using the viscosity equations of McAllister and Heric. The values of the quantity {Delta}{eta}, which refer to the derivations of the experimental values of the dynamic viscosities of the mixtures from the mole fraction mixture law values, have been found to be positive for all the mixtures. The deviations in viscosity data {Delta}{eta} have been fitted to the Redlich-Kister polynomial relation to estimate the binary coefficients. Also, the values of the parameter d{sub 12} have been calculated from the equation ln {eta} = x{sub 1} ln {eta}{sub 1} = x{sub 2} ln {eta}{sub 2} + x{sub 1}x{sub 2}d{sub 12}, where {eta}{sub 1} and {eta}{sub 2} refer to the dynamic viscosities of the two pure liquids 1 and 2 whose mole fractions in the mixture are x{sub 1} and x{sub 2}, respectively. The values of d{sup 12} indicate the existence of a specific interaction between dissimilar molecules.
