EXCESS PROPERTIES OF THE BINARY-LIQUID SYSTEM PROPYLENE CARBONATE + ACETONITRILE

Dielectric constants, densities, viscosities, and refractive indices for the propylene carbonate + acetonitrile system were determined over the entire composition range of the system and at various temperatures, ranging from 25 to 45-degrees-C. Excess dielectric constants, excess volumes, excess viscosities, and excess Gibbs energies of activation of the viscous flow, as well as Kirkwood correlation factors, have been calculated and studied. Their behavior strongly suggests the existence of intermolecular interactions.
