Abstract
Apparent molar volumes, Φv, and isentropic compressibilities, κs, of the aqueous solutions of anionic surfactant, sodium dodecylbenzene sulfonate (SDBS), have been derived from experimental densities, ρ, and speed of sound, u, data measured below 0.40 mol·kg−1 at T = (298.15, 303.15, 308.15, and 313.15) K using an Anton Paar densimeter (DSA-5000). Conductance measurements were also made for aqueous solutions of SDBS to obtain critical micelle concentration at the above temperatures. Apparent molar volumes and isentropic compressibilities of 1-pentanol and 1-hexanol dissolved in aqueous micellar solutions of SDBS were determined as a function of molalities of surfactant (0.05 and 0.1) mol·kg−1 and alcohols at T = (298.15 and 308.15) K. The standard partial molar volumes, Φov, and transfer volume, Φov(tr), have been calculated for rationalizing various interactions in the studied solutions. Viscosity measurements were made for the above-mentioned alcohols in aqueous solutions of SDBS to obtain relative visc...
