| 摘要: | The equilibria occurring in aqueous solutions of 4-methyl-4,7-diazadecanediamide (4-Me-L-2,2,2),4,7-dimethyl-4,7-diazadecanediamide (4,7-N,N’-Me2-L-2,2,2) ,4-ethyl-4,7-diazadecanediamide (4-Et-L-2,2,2), and 4-methyl-4,8-diazaundecanediamide (4-Me-L-2,3,2) with protons and nickel(II) ions as well as the deprotonation reactions of the nickel(II) complexes of these four ligands have been studied by calorimetry at T=25.0℃ and μ=0.10M(KCl).The enthalpy changes and the entropy changes for these reactions are reported and discussed. |
