摘要： 利用量热法测定了298.15K时葡萄糖在一些醇(甲醇、乙醇、1-丙醇、1-丁醇)与甲酰胺的混合溶剂中的溶解热.采用McMilan-Mayer方法,将溶液热力学过量性质与溶液中粒子的相互作用参数相关联,求得了粒子间的焓对相互作用参数和三分子相互作用参数,并就溶质-溶质间的相互作用及溶剂的影响进行了讨论.

关键词: 焓相互作用参数, 葡萄糖, 醇, 甲酰胺

Abstract: The molar enthalpies of glucose solution, in the mixtures of some alcohols and formamide(FA), have been determined at 298.15K by using a C-80 colarimeter. The McMillan-Mayer theory was used to relate the excess enthalpies of the system to a series of pair and triplet interaction parameters. From the experimental results, the values of pair and triplet interaction parameters hXY, hXYY, hXXY between solutes have been fitted by a least square method.The information about the solute-solute interaction and the effect of solvent on the interaction were discussed.

Key words: Enthalpy interaction parameter, Glucose, Alcohol, Formamide
