Viscosity of binary mixtures of alkyl acetates with hexane, tetrachloromethane, and trichloromethane

The viscosity eta for binary mixtures of methyl acetate (MA), ethyl acetate (EA), n-amyl acetate (nAA), isoamyl acetate (IAA), decyl acetate (DeA), an d dodecyl acetate (DoA) with hexane and of MA, EA, nAA, and iAA with tetrac hloromethane and trichloromethane has been measured at 303.15 K over the en tire range of composition. The viscosity data have been correlated with the equations of Grunberg and Nissan; Hind, McLaughlin, and Ubbelohde; Tamura and Kurata; Katti and Chaudhri; McAllister; Heric and Brewer; and Auslaende r. The viscosity deviations Delta eta and excess Gibbs energy of activation Delta G*(E) of viscous flow based on Eyring's theory have been calculated. The results have been analyzed in terms of disruption of dipolar associati on of alkyl acetate and molecular interaction between alkyl acetate and chl oromethane.
