Temperature dependence of the densities and speeds of sound of the binary solutions of LiClO₄ with diethyl ether, tetrahydrofuran, acetone, and ethyl acetate

Abstract

Densities, ρ, and speeds of sound, u, of the solutions of LiClO₄ with diethyl ether, tetrahydrofuran, acetone, and ethyl acetate are reported from 288.15 K to 338.15 K. At 298.15 K, measurements have been made up to ≈5.37, 1.12, 4.78, and 3.61 mol kg^-1 of LiClO₄ in diethyl ether, tetrahydrofuran, acetone, and ethyl acetate, respectively. At other temperatures, densities and sound velocities are measured to m <0.2 mol kg^-1 in order to calculate the infinite dilution apparent molal volumes, φ_V^o, and compressibilities, φ_K^o, in different solvents. The ρ and u data for these solutions can be analyzed by Pitzer equations with average standard deviations, σ, as 0.08 kg m^-3 and 0.5 m s^-1, respectively.
