In order to obtain the standard molar enthalpies of formation of Rare-Earth amino acid coordination compounds, precise isothermal solution-reaction calorimetric method was used. The value of ΔrH of two coordination reactions was determined at T=298.2 K. From the experimental results and other auxiliary values, the standard molar enthalpies of formation of Ln(Gly)5/2(Ala)3/2(ClO4)3·H2O(s) [Ln=La, Yb] at T=298.2 K were obtained. The values of them is to be ΔrH[La(Gly)5/2(Ala)3/2(ClO4)3·H2O(s)]=−3545.45 kJ/mol and ΔrH[Yb(Gly)5/2(Ala)3/2)(ClO4)3·H2O(s)]=−3793.81 kJ/mol, respectively. [ABSTRACT FROM AUTHOR] |
