The present investigation deals with the theoretical estimation of viscosity of two binary liquid mixtures of 2-Propenol and 2-Phenylehanol or Benzyl alcohol over the entire range of mole fractions at elevated temperatures from 298.15-318.15K and atmospheric pressure by six empirical relations such as Eyring, Bingham, Kendall-Munroe, Frenkel, Dey and Hind. Computed values of viscosities obtained by the aforementioned relations were compared with the experimental findings. Deviation in viscosity ( ∆η ) was derived from measured data and fitted to redlich-kister polynomial to estimate the binary coefficient and standard deviation. Excess molar volume (VE) was also computed to analyze the extent of molecular interactions and Furthermore, Joubyan Acree model is used to correlate the experimental findings. Eyring, Hind, and Frenkel models show the best agreement with experimental data. Copyright@ International Science Community Association
