Abstract

Viscosities of three associated binary mixtures, viz., chlorobenzene + benzylalcohol, chlorobenzene + n-hexanol and n-hexanol + benzylalcohol have been determined at different temperatures over the complete composition range. Using viscosity-composition-temperature data, excess viscosities and the energies of activation for viscous flow have been obtained and their variations with composition have been discussed. Also, the predicitive abilities of a few of the existing equations for mixture viscosities have been compared.
