摘要: 利用气液色谱方法测定了298.15K时若干非电解质溶质在甲酰胺-乙酰胺、甲酰胺-尿素、甲酰胺-高氯酸钠固定液中的保留参数。采用McMillan-Mayer理论,将溶液热力学过量性质与溶液中粒子的对相互作用、叁相互作用参数相联系。利用热力学方法求得了溶质的保留参数与Gibbs自由能相互作用参数的关系。并就溶质-溶质间的相互作用及溶剂性质的影响进行了讨论。

Abstract: The retention values of eight organic solutes in stationary solution of formamide+ acetamide, formamide + urea and formamide + sodium perchlorate at the temperature of 298.15 Kwere measured by a gas-liquid chromatographic method(GLC.The McMillan Mayer's solution theory was used to relate the excess Gibbs free energy of the system to a se ries of pair and triplet interaction parameters. The relationship of the interaction parameters with the retention values of GLC was deduced by using the thermodynamic method.From experimental result, the values of pair and triplet interaction parameters, gij and gijj,be tween solutes have been fitted by a least square method.The information about the solute solute interaction and the effect of solvent on the interaction have been discussed.

Key words: Gibbs free energy interaction parameter, Gas liquid chromatographic method, Amide, Urea, Sodium Perchlorate
