Thermochemistry study on the complexes RE（HSal）3·H2O（RE=Eu,Gd,Tb）
【摘要】 目的研究配合物RE(HSal)3.H2O(HSal=C7H5O3;RE=Eu,Gd,Tb)的热化学性质。方法采用燃烧量热法。结果合成了3种稀土水杨酸配合物RE(HSal)3.H2O(RE=Eu,Gd,Tb)。在298.15 K下,用精密转动弹热量计测定出配合物的恒容燃烧能ΔcU,分别计算出它们的标准摩尔燃烧焓ΔcH m和标准摩尔生成焓ΔfH m。结论确定了配合物的组成,得到的热力学数据为扩大应用范围提供了理论基础。
【Abstract】 Aim To study the thermchemical properties of complexes RE(HSal)3·H2O(HSal=C7H5O3;RE=Eu,Gd,Tb).Methods Combustive calorimetry.Results Three rare earth complexes with salicylic acid RE(HSal)3·H2O(RE=Eu,Gd,Tb) were synthesized.Their constant-volume combustion energies,ΔcU were determined using a precise rotating-bomb calorimeter at 298.15 K.Their standard molar combustion enthalpies,ΔcHθm,and standard molar formation enthalpies,ΔfHθm,were calculated respectively.Conclusion The composition of the complexes were confirmed by elemental analysis and IR spectra.
