Abstract

An isobaric equation of state of a binary solution with hydrogen bonds is derived using the thermodynamic grid model. Temperature dependences of the molecular and bond concentrations are calculated. The dependences demonstrate phase transitions, for which both concentrations serve as the order parameters. It is shown that this bicomponent can give rise to new properties of the solution. In particular, there is a threshold hydrogen bond energy over which condensation of hydrogen bonds occurs in a certain range of molecular concentrations.

具有交叉氢键的液体溶液中的分层相变：键数密度为二阶参数

摘要

使用热力学网格模型导出具有氢键的二元溶液的等压状态方程。计算分子和键浓度的温度依赖性。依赖性证明了相变，对于这两个浓度，这两个浓度都用作阶跃参数。结果表明，这种双组分可以产生溶液的新性质。特别地，存在阈值氢键能量，在该阈值氢键能量上，在一定的分子浓度范围内发生氢键的缩合。
