Apparent molar volumes and compressibilities of α- and β-cyclodextrin in aqueous sulfamethoxazole at different temperatures

The apparent molar volumes, Vϕ, apparent molar adiabatic compressibilities, Kϕ , s, apparent molar volumes at infinite dilution, Vϕ0, and apparent molar adiabatic compressibilities at infinite dilution, Kϕ , s0 are evaluated from the measured densities, ρ, and speeds of sound, u, values, for α-cyclodextrin and β-cyclodextrin in aqueous sulfamethoxazole solutions at T = (288.15, 293.15, 298.15, 303.15, 308.15) K. Further, transfer partial molar volume, ΔVϕ0 at infinite dilution, transfer partial molar adiabatic compressibilities, ΔKϕ , s0 at infinite dilution and pairwise and triplet interaction coefficients, are discussed in terms of solute-solute and solute-solvent occurring in the ternary solution of present study.
