| 摘 要： | 本文用LKB-2277 BioActivity Morator测定了298.15K时乙酸在水和乙醇,水和N,N二甲基甲酰胺(DMF)两种混合溶剂中电离焓。并用溶液中溶质与溶剂相互作用的观点,对乙酸在上述两种混合溶剂中电离焓的区别及变化趋势进行了简单的讨论。

| Abstract: | The ionization enthalpies of acetic aicd at 298.15Kin H2O-EtoH mixtures and in H2 O-DMF mixtures were measured by LKB-2277 Bioactivity Monitor.The diff-erences between enthalpies of acetic acid in H2O-EtoH mixtwres and in H2O-DMF mixtures were discussed simply in view of the solute-solvent interactions in solution. |
