Viscometric investigation of binary, ternary and quaternary liquid mixtures: Comparative evaluation of correlative and predictive models

Transport properties provide a deep and meaningful insight of the various interactions taking place in binary and higher component liquid mixture. Literature reveals scarcity of data on ternary and higher order multicomponent liquid mixtures. Absolute viscosities of four binary, one ternary and one quaternary systems containing benzene, cyclohexane, n-hexane and n-decane at 298.15K have been evaluated. These systems have significant usage and applications in multifarious industries, viz., chemical, pharmaceutical, and petrochemical. Sixteen approaches have been employed involving empirical, semi-empirical, correlative and predictive models including McAllister 3 and 4 body, Grunberg–Nissan, Wijk, Hind, Katti-Chaudhri and Tamura–Kurata. The absolute average percentage deviations (AAPDs) have been used to compare their predictive capabilities. The modified McAllister relation, which employs the ECN approach developed for 308K, shows its versatility by proving its validity even at 298.15K.
