Abstract

Densities and viscosities at (298.15, 308.15, and 318.15) K are presented as a function of mixture composition for the binary mixtures of ethyl lactate with methacrylic acid, benzyl methacrylate, and 2-hydroxyethyl methacrylate. From the experimental data, the excess molar volumes V E and viscosity deviations δη have been calculated. These results have been correlated with the Redlich−Kister type polynomial to derive the coefficients and standard deviation σ. McAllister's three-body and four-body interaction models were also used to correlate the kinematic viscosities. These model's parameters were treated to be temperature dependent.
