ABSTRACT
The present study reports the densities, rho and speeds of sound, u of monosaccharides (D (+) -xylose and D (-)-ribose) in aqueous triammonium citrate (TAC) solutions at temperatures, T = (288.15, 298.15, 308.15 and 318.15) K and at experimental pressure, p = 0.1 MPa. The available data is used to calculate the thermophysical parameters like apparent molar volumes Vphi, apparent molar isentropic compressibilities Kphi,s, partial molar volumes, Vphio and partial molar isentropic compressibilities, Kphi,soand then the partial molar volumes of transfer, deltaVphioand partial molar isentropic compression of transferdeltaKphi,soare evaluated. Further, the expansion coefficients, (dVphi0/dT)p, (d2Vphi0/d2 T)p, pair (VAB, KAB) and triplet (VABB, KABB) interaction coefficients have also been determined. These parameters have been discussed to ascertain the solute co-solute interactions. Apparent specific volumes ASV and hydration numbers Nw are also calculated to check the taste behaviour and hydration behaviour respectively.
