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

The apparent molar volumes, V-phi, apparent molar adiabatic compressibilities, K-phi,K-s, apparent molar volumes at infinite dilution, V-phi(0), and apparent molar adiabatic compressibilities at infinite dilution, K-phi,s(0), are evaluated from the measured densities, rho, and speeds of sound, u, values, for alpha-cyclodextrin and beta-cyclodextrin in aqueous sulfa-methoxazole solutions at T = (288.15, 293.15, 298.15, 303.15, 308.15) K. Further, transfer partial molar volume, Delta V-phi(0) at infinite dilution, transfer partial molar adiabatic compressibilities, Delta K-phi,s(0) 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.
