Thermodynamic characteristics of the acid–base equilibria of ethylenediamine-N,N′-diglutaric acid in aqueous solutions using calorimetric data

Аннотация

The enthalpies of reaction of betaine group neutralization of ethylenediamine-N,N'-diglutaric acid (H₄L) at 298.15 K and at different values of ionic strength of 0.1, 0.5, 1.0 (KNO₃) is measured by direct calorimetry. The standard thermodynamic characteristics of the protolytic equilibria of H₄L are calculated.
