葡萄糖、果糖和蔗糖在甲酰胺溶液中的体积性质

Volumetric Properties of Glucose,Fructose and Sucrose in Formamide

报导了含葡萄糖、果糖和蔗糖的甲酰胺溶液的密度数据，无限稀释表观摩尔体积和体积第二维里系数．利用改进的定标粒子理论、基团几何模型和基团加合方法，求解了溶质的空腔生成体积，溶质-溶剂间的氢键作用对体积性质的影响，并和水溶液中的情况进行了比较．

Densities of binary mixtures of glucose,fructose and sucrose with formamide solveng were measured at 298.15K. From these data,the apparent molar volumes of carbohydrates at infinite dilution were obtained.The cavity volume and the interaction volume between solute and solveut were evaluated by two methods.One is a modified scaled particle theory,which takes into account of the real molecular shape.Another is a combination of a geometrically consideration with a group additive approach, which can be used to analyze molecules of arbitrary shape.The calculated results by these two methods were compared with the results in water.
