Stability, Kinetics of Acid Decomposition of Cu(Ⅱ) Complexes of Novel Polyamide-polyamino Ligand

Abstract

Abstract: A polyamide polyamino ligand was synthesized. The stability constants of its copper (Ⅱ) complexes at 5, 10, 15 and 25 ℃ were determined. The standard molar entropy of formation ΔS_m⁰ and standard molar enthalpy of formation ΔH_m⁰ were obtained and used to discuss the effect of temperature on the stability of the complexes. The acid decomposition of CuL assisted by 0.04—2.34 mol/L(I= 2.34 mol/L NaCl) hydrochloride was investigated by using stopped-flow technique. The mechanism was given and the activation energy E_a, standard molar entropy of activation Δ^≠S_m⁰ and standard molar enthalpy of activation Δ^≠H_m⁰ of the rate-determining step were calculated.
