双安息香缩乙二胺合Fe(Ⅱ)Co(Ⅱ)Ni(Ⅱ)配合物的合成双氧合性能

SYNTHESIS AND OXYGENATION PROPERTY OF Fe(Ⅱ),Co(Ⅱ) AND Ni(Ⅱ ) - (BIS-BENZOIN SEMIETHYLENEDIAMINE) COMPLEXES

研究合成了3种新的Schiff碱配合物：双安息香缩乙二胺（H2L1）合Co（Ⅱ）、Fe（Ⅱ）和Ni（Ⅱ）．通过元素分析，红外光谱、摩尔电导和磁矩测定方法对配合物予以表征用常规气体吸收容量测量装置测得配合物在DMF溶剂中不同温度下的饱和吸氧量，并研究了配合物氧合反应的热力学．

Three schiff base complexes of Fe(Ⅱ ),Co(Ⅱ)alld Ni (Ⅱ) have been synthesized in yield more than 90% by the reaction of metal salts with bis-benzoin-semiethylene diamine in CHCl3. They are all characterized by elemental analysis, IR and the determinations of molar conductivity and magetic moment. The satunated oxygen uptake of these complexes in DMF solvent is obtaninned by manwmetric uptake measurements and is about one mmolar O2 per mmolar complex at -15℃. Their oxyenation equilibrium constants and thermodynamic parameters △H0 and △X0 is calculated from the above measurements.
