Excess thermodynamic properties of mixtures of alkyl benzoates with n-heptane

Abstract

The paper reportsh E values at 298.15 K andv E and δη values at various temperatures for binary mixtures of propyl or butyl benzoate andn-heptane. The excess Gibbs energy of viscous flow,Δg *E, and the thermodynamic activation properties were calculated from these values. The results are compared with those for similar mixtures and interpreted on the basis of the characteristic dipole-dipole interactions of alkyl esters.
