The relative viscosities ηr of anilinium chloride solutions in a series of isopropanol-water mixtures have been determined at 20°, 30°and 40℃, using Ubbelohde-type viscometers. The viscosity data have been interpreted in terms of viscosity A-and B-coefficients calculated from the Jones-Dole equation, ηr = 1 + AC1/2+ BC. The energy of activation for viscous flow have also been calculated according to the concept of rate processes. The results indicate that at 0.10∼0.15 mole fraction isopropanol the maximum structuredness of water gives a minimum values of viscosity A-and B-coefficients, and that anilinium chloride belongs to the borderline case in respect of the structure-making or structure-breaking effects on water.
