摘要
Density measurements have been carried out at T = 298.15 K for the CsCl-monosaccharide (D-galactose, D-xylose and D-arabinose)-water systems. The apparent molar volume of saccharides V-phi,V-S in the ternary solutions, the corresponding infinite dilution apparent molar volume V(phi1S)degrees, and the standard transfer volume Delta(t)V(phi1S)degrees of saccharides from water to aqueous CsCl solutions have been determined. The McMillan-Mayer theory was employed to relate the excess thermodynamic functions to a series of interaction parameters to obtain the volumetric interaction parameters of CsCl with monosaccharide in water. These parameters are interpreted by the group additivity principle and the stereochemistry of these monosaccharide molecules. (C) 2004 Elsevier Ltd. All rights reserved.
