摘要： 用气液色谱法测定了298.15K时10个非电解质溶质在不同浓度甲酰胺糖(葡萄糖,果糖,蔗糖)溶液中的保留参数.依据McMillanMayer理论,求得非电解质溶质与糖间的Gibbs自由能相互作用参数gij和gijj.采用OkamotoWood的基团加合法,求得各基团的Gibbs自由能相互作用参数Gx,y,讨论了非电解质溶质与糖间的相互作用以及溶剂性质的影响.

Abstract: The retention values of ten non-electroltyes in stationary solution of formamide-glucose, formamide-fructose and formamide-sucrose at 298.15 Kwere measured by a gas-liquid chromatographic method(GLC). Depending on the McMillan-Mayer theory, the values of pair and triplet interaction parameters gij andgijj of saccharides with non-electroltyes have been evaluted. The group interaction Gibbs free energy parametersGx,y were evaluted by the Okamoto-Wood group additivity method. The information about the solute-solute interaction and the effect of solvent were discussed.

Key words: Gibbs energy interaction parameter, Group additivity, Gas-liquid chromatographic method, Saccharide, Non-electrolyte, Formamide
