A new unsymmetrical solid Schiff base (HLLi) was synthesized using L-lysine, salicylidene and furfural. Solid samarium(Ⅲ) complex of this ligand [Sm(HL)(NO3)](NO3)·2H2O was prepared and characterized by elemental analyses, IR, UV and molar conductance. The thermal decomposition kinetics of the complex for the second stage was studied under non-isothermal condition by TG and DTG methods. The kinetic equation may be expressed as: dα/dt=A·e-E/RT·(1-α)2. The kinetic parameters(E, A), activation entropy ΔS≠ and activation free-energy ΔG≠ were also gained, E=213.8 kJ·mol-1, lnA=43.93, ΔS≠=115.2 J·mol-1·K-1, ΔG≠=150.1 kJ·mol-1.
A new unsymmetrical solid Schiff base (HLLi) was synthesized using L-lysine, salicylidene and furfural. Solid samarium (Ⅲ) complex of this ligand [Sm (HL) (NO3) · 2H2O was prepared and characterized by elemental analyzes , IR, UV and molar conductance. The thermal decomposition kinetics of the complex for the second stage was studied under non-isothermal condition by TG and DTG methods. The kinetic equation may be expressed as: dα / dt = A · eE / RT · (1-α) 2. The kinetic parameters (E, A), activation entropy ΔS ≠ and activation free-energy ΔG ≠ were also gained, E = 213.8 kJ · mol -1, lnA = 43.93, ΔS ≠ = 115.2 J · mol-1 · K-1, ΔG ≠ = 150.1 kJ · mol-1.
