摘要：

The density and ultrasound propagation velocity for Et4NBF4 solutions in propylene carbonate were determined in a concentration range of 0.01-0.8 mol/kg at 283.15, 298.15, and 308.15 K. Apparent molar compressibilities and volumes of the studied electrolyte in solvent were calculated. Solvation numbers and molar adiabatic compressibilities of solvate complexes were determined using the isoentropic compression method. These quantities indicated weak solvation of tetraethylammonium tetrafluoroborate in propylene carbonate in the range of concentrations practically used in ionistors.
