摘　　要：根据实验结果获得了 2 98 15K碱金属氯化物 乙醇在水中的焓对作用系数 ,并引述了部分文献值 ,对它们进行了分析和讨论 .将基团加和性的概念应用于NaCl,NaI 非电解质的相互作用 ,得到官能团相互作用参数hNi.Enthalpic pair interaction coefficients of alkalic metals chloride enthanol in water at 298 15?K were determined according to the experimental results. In addition to our own experimental results, we incorporated some data reported by literature. Analyses and discussions were carried out. A functional group additivity concept was applied to the interactions between NaCl, NaI and nonelectrolytes. Functional group interaction parameters h Ni were obtained.
