摘要
借助M(NTO)n.mH2O(M=La,Ce,Pr,Eu,Sm,Gd,n=3,m=7;M=Y,Yb,n=3,m=6;M=Dy,Tb,n=3,m=5;M=Nd,n=3,m=8)在水中的溶解焓ΔsolHmθ、晶格焓ΔHLθ、晶格能ΔULθ和标准生成焓ΔfHmθ(Mn+,aq,∞)、ΔfHmθ(Mn+,g)、ΔfHmθ(H2O,g)、ΔfHmθ(H2O,l)、ΔfHmθ(NTO-,aq,∞)、ΔfHmθ(NTO-,g)以及Mn+的水合焓ΔhHmθ(Mn+)的文献数据,估算了NTO负一价离子的水合焓ΔhHmθ(NTO-),结果显示,ΔhHmθ(NTO-)=-(153.73±0.21)kJ.mol-1。
Based on the literature data of the enthalpies of solution in water,△solHm^θ, lattice enthalpy, △HL^θ,lattice energy,△UL^θ for the complexes of the lanthanidi metals with 3-nitro-1,2,4-triazol-5-one ( NTO ), M ( NTO )n · mH2O ( M = La, Ce, Pr, Eu, Sin, Gd, n=3,m=7; M =Y,Yb,n=3,m =6; M =Dy,Tb,n =3,m =5; M = Nd,n =3,m =8),standard enthalpies of formation, △fHm^θ(M^n+ ,aq,∞ ) ,△fHm^θ(M6n+ ,g) ,△fHm^θ(H2O,g) ,△fHm^θ(H2O,l) ,△fHm^θ(NTO^-,aq,∞ ) ,△fHm^θ(NTO^- ,g) and hydrous enthalpy of M^a+, △fHm^θ(M^a+ ) ,the hydrous enthalpy of NTO^-, △hHm^θ (NTO^- ) was estimated as - (153.73 ±0.21) kJ· mol^-1.
