Abstract
Densities and viscosities of binary liquid mixtures of butyl acrylate + 1-butanol and ethyl laurate + 1-butanol are presented over the complete concentration range at (293.15, 303.15, and 313.15) K. The densities were measured using a vibrating tube digital densimeter, and the viscosities were measured by a capillary viscometer. Excess molar volumes and viscosity deviations were then calculated at various temperatures. All excess molar volumes are positive, indicating the effect of disruption of the hydrogen bonding between 1-butanol molecules. Excess molar volumes and viscosity deviations were correlated by the Redlich−Kister type equations. Optimally fitted parameters are presented, and the correlation results are in satisfactory agreement with the experimental data.
