The standard partial molar volumes, V-2 degrees, at infinite dilution of eight monosaccharides [D(+)-xylose, D(-)-arabinose, D(-)-ribose, L(-)-sorbose, D(-)-fructose, D(+)-galactose, D(+)-glucose, and D(+)-mannose], six disaccharides [D(+)-cellobiose, sucrose, D(+)-melibiose, D(+)-lactose rnonohydrate, D(+)-trehalose dihydrate, and D(+)-maltose monohydrate] and two trisaccharicles [D(+)-melizitose and D(+)-raffinose penta-hydrate] (molalities of saccharides range from (0.03 to 0.12) mol . kg(-1)) have been determined in water and in (0.5, 1.0, 2.0, and 3.0) mol . kg(-1) aqueous sodium acetate solutions at temperatures, T = (288.15, 298.15, 308.15, and 318.15) K from density measurements using a vibrating-tube digital densimeter. From these results, corresponding standard partial molar volumes of transfer, Delta V-t(2)degrees have been determined for the transfer of various saccharides from water to aqueous solutions of sodium acetate. Positive values of Delta V-t(2)degrees were obtained for most of the saccharides, whose magnitude increase with the concentration of sodium acetate as well as temperature. However, negative Delta V-t(2)degrees values were observed for L(-)-sorbose, D(-)-fructose and D(+)-xylose at lower concentrations of co-solute. The negative magnitude of Delta V-t(2)degrees values decrease with rise of temperature from (288.15 to 318.15) K. Pair and higher order volumetric interaction coefficients have been determined by using McMillan-Mayer theory. Partial molar expansion coefficients, (partial derivative V-2 degrees/partial derivative T)(p) and the second derivatives (partial derivative V-2(2)degrees/partial derivative T-2)(p) have also been estimated. These parameters have been utilized to understand various mixing effects in aqueous solutions due to the interactions between solute (saccharide) and co-solute (sodium acetate).
