viscometric st udies of b inary mix tures of formamid e with alkan-۲-ols

excess viscosities fo r binary liquid mixture s of forma mide with (C۳-C۷) alkan-۲-ols ha ve been cal culated from the viscosities measured at ۲۹۸.۱ ۵ K over the whole co mposition.T he viscosity-mole fraction data of th e five systems were use d to test law proposed to describe t he viscosity of mixtures : the mod el by Redlic h-Kister we re tested. D eviations with respect to ideal behaviour were interpreted in terms of specific interactions between unlike molecules
