Summary, etc. <p>The viscosities (<em>h</em>) of binary mixtures of methyl acrylate with 1-butanol, 1-hexanol, 1-octanol and 1-decanol, including those of pure liquids, over the entire composition range are reported at different temperatures (288.15, 293.15, 298.15, 303.15, 308.15, 313.15, and 318.15) K. From the experimental data, the deviations in viscosity (D<em>h</em>) have been calculated. The D<em>h</em> values are found to be negative over the entire composition range for these mixtures, indicating the presence of weak interactions between methyl acrylate and 1-alkanol molecules. The magnitude of negative deviations in D<em>h</em> values follows the order: 1-butanol &lt; 1-hexanol &lt; 1-octanol &lt; 1-decanol. It is observed that D<em>h</em> values depend upon the length of the alkyl chain in 1-alkanols. Also, the interactions between methyl acrylate and 1-alkanols decrease with increase in alkyl chain length. The thermodynamics of viscous flow has been analyzed by using Eyring and Arrhenius approaches and the results have been compared and discussed in terms of intermolecular interactions between the molecules. Further, the viscosities of these binary mixtures computed theoretically by using various empirical and semi-empirical models correlated well with the experimental findings in terms of average standard deviations.</p>
