Abstract

Abstract Solutions of tetraethylammonium tetrafluoroborate in propylene carbonate were studied by viscometry and densimetry over the concentration range 0.08–1 mol/kg at 283.15, 298.15, and 308.15 K. The concentration dependence of the viscosity of solutions was described by the Angell and Bachinskii equations. The thermodynamic parameters of activation of viscous flow of solutions of Et 4 NBF 4 in propylene carbonate were estimated ...
