ABSTRACT

The densities, q and speeds of sound, u of D(+)-glucose and D( )-ribose in water and in (0.10, 0.20, 0.30, and 0.40) mol kg 1 aqueous protic ionic liquid (3-hydroxy propylammonium formate) solutions were measured at temperatures, T = (298.15 to 318.15) K. Infinite dilution standard partial molar volume, V12 and standard partial molar isentropic compressibility, K1 s;2 have been calculated, which were used to evaluate the standard transfer volumes, DtV12 and DtK1s ;2. The DtV12 and DtK1s ;2 values for monosaccharides decrease in the order: D(+)-glucose greater than D( )-ribose. The transfer parameters are positive and increase with molalities of ionic liquid (IL) and with temperature. Further, the expansion coefficients, (dV2 /dT)P, its derivative (d2V2 /dT2)P, pair (VAB and KAB) and triplet (VABB and KABB) volumetric interaction coefficients and hydration numbers, Nw have also been calculated and used to discuss the solvation behaviour of monosaccharides. The variation in the taste quality of monosaccharides in the presence of IL has also been studied from apparent massic volume, v/ and apparent massic isentropic compressibility, K/,m parameters.
