THERMODYNAMIC AND STRUCTURAL PROPERTIES OF AQUEOUS SOLUTIONS OF SELF-ASSOCIATED ALKANOLAMINES
Thermodynamic characteristics are calculated for aqueous solutions of self-associated alkanolamines, which are capable of forming hydrogen bond networks. Correlations are found between the thermodynamic properties and structure of the solutions. The correlation between the entropy and enthalpy characteristics of water-alkanolamine systems with excess packing coefficients suggests that universal interactions determine the structural and energy properties of aqueous solutions of alkanolamines being studied. The structural and thermodynamic characteristics of aqueous solutions of self-associated alkanolamines are found to be similar to the previously obtained parameters of aqueous solutions of diols and oxyethylated glycols.
