摘要
提出了一个醇与水混和的热力学模型 ,它由三步组成 ,分别考虑了醇与水的物理混合 ,醇和水的自缔合破坏以及它们间的交叉缔合 .据此建立了一个超额焓方程 .检验的结果表明 ,它能满意地描述含醇水溶液的超额焓随组成和温度的变化规律 .
A thermodynamic model of the formation of aqueous solutions of alcohol is proposed. It is composed of three steps which take account of physical mixing, destructions of self association and cross association for alcohol and water, respectively. An excess enthalpy equation is established based on this thermodynamic model. The results of test show that the equation can be satisfactorily used to describe the rule of variation of excess enthalpy with composition and temperature for aqueous solutions of alcohol.
