Abstract
Densities and speed of sound measurements of two mono-saccharides D(−)-ribose and D(+)-xylose have been taken in water and in aqueous trisodium citrate in concentration (0.2, 0.4, and 0.6) mol kg− 1 at T = (288.15, 298.15, 308.15 and 318.15) K and atmospheric pressure. Apparent molar volumes (V ϕ), apparent molar volumes at infinite dilution (Vϕ0) and corresponding transfer apparent molar volumes (ΔVϕ0), partial molar expansion coefficients (∂Vϕ0/∂T)P and their second derivative (∂2Vϕ0/∂T2)P, isentropic compression (Kϕ,S), isentropic compression at infinite dilution (Kϕ,S0), transfer apparent molar isentropic compression at infinite dilution (ΔKϕ,S0) have been calculated using experimental density and speed of sound data. The results have been discussed in terms of different types of interactions occurring in the present system.
