英文摘要dilution enthalpies and mixing enthalpies of sodium halide and some saccharides (glucose, galactose, xylose, arabinose, fructose, and sucrose) in aqueous solution were determined by calorimetric measurements at 298.16 k. the values were used to determine enthalpic pair interaction parameters. combined with gibbs energy pair parameters, entropic pair interaction parameters were also obtained. theoretical calculations at the b3lyp/6-311++g(d,p) level were carried out to provide the information of structures and thermodynamic functions. the information reveals the thermodynamic essence of the interactions between sodium halide and saccharides in aqueous solutions. the experimental results and theoretical calculations show that the sign of enthalpic pair interaction parameter 2vh(es) is determined by the direct interaction between saccharides and ions, whereas the difference in value of 2vh(es) for different saccharides or electrolytes depends on the partial dehydration of saccharides or anions in aqueous solution. the difference in value of entropic pair interaction parameters depends partly on the different dominant interactions in the process of partial dehydration of saccharides or ions. an enthalpy-entropy compensation relationship was observed for the sodium bromide-aldopyranose-water systems. remarkably, it can be conjectured that the hydration entropy of glucose is lower than for, other monosaccharides. perhaps it is one of the reasons why glucose plays an important role in living organisms rather than other monosaccharides.
