摘要: 本文根据定标粒子溶液理论计算了KCl、KBr、NaCl、NaBr、CsCl和CsBr在DMSO、DMF、MeOH、(CH3)2CO、MeCN、EtOH和H2O中的溶剂化自由能,涉及的离子-溶剂间静电相互作用能,用“一层连续介质模型”所给出的公式计算,结果与实验符合很好。

Abstract: This paper has calculated ionic solvation free energies of KCl, KBr, NaCl, NaBr, CsCl and CsBr in seven solvents namely DMSO, DMF MeOH, MeCN, (CH3)2CO, EtOH and H2O. The results agree with observed values pretty well. Aone-layer continuum model was adopted in calculation, the nonelectrostatic term was calculated by the equation of scaled particle theory.
