摘要：

Accurate viscosity and permittivity data are reported for the organic solvent system propylene carbonate + acetonitrile covering the solvent composition range from pure propylene carbonate to pure acetonitrile at temperatures from -35 to 35-degrees-C. Accurate density and conductivity data were determined for solutions of LiClO4 in these solvents covering the whole concentration range from infinite dilution to saturation. Evaluation of the limiting conductivity LAMBDA0 and the association constant K(A) is performed on the basis of a conductivity equation that includes concentration terms up to c3/2. Concentrated solutions are analysed in terms of the Casteel-Amis equation. Correlations of limiting conductivity LAMBDA0 versus the maximum specific condUCtiVity kappa(max) and of kappa(max) versus the molality mu at maximum specific conductivity are discussed.
