Densities and Speeds of Sound of d(+)-Glucose, d(−)-Fructose, d(+)-Xylose and d(−)-Ribose in Aqueous Tripotassium Citrate Solutions at Different Temperatures

Apparent molar volumes (V_ϕ) and apparent molar isentropic compressions (K_ϕ,S) for some monosaccharides {d­(+)-glucose, d­(−)-fructose, d­(+)-xylose and d­(−)-ribose} in (0.0, 0.2, 0.4, 0.6) mol·kg^–1 aqueous solutions of tripotassium citrate (TPC) have been determined from density and speeds of sound measurements along four isotherms at temperatures between (288.15 and 318.15) K at experimental pressure p = 0.1 MPa using an automated vibrating tube densimeter (Anton Paar DSA 5000 M). The experimental values are used to determine partial molar volume (V_ϕ⁰), partial molar isentropic compression (K_ϕ,S⁰) at infinite dilution and their corresponding partial molar volumes of transfer (ΔV_ϕ⁰), and partial molar isentropic compression of transfer (ΔK_ϕ,S⁰). The expansibility parameter (∂V_ϕ⁰/∂T)_P and its derivative (∂²V_ϕ⁰/∂T²)_P along with pair (V_AB, K_AB) and triplet (V_ABB, K_ABB) interaction coefficient for density and speed of sound data have been determined. The interpretation of the data has been made in terms of solute–solvent interactions.
