采用磺胺噻唑与对羟基苯甲醛合成一种新西佛碱，并将此配体制备８种稀土配合物．通过元素分析、红外光谱、核磁共振、热分析、摩尔电导和溶解性质对配合物进行了表征．配合物的组成为两种型式：ＲＥＬ（ＯＨ）１．５Ｈ２Ｏ和ＲＥＬ（Ｃｌ）１．５Ｈ２Ｏ（ＲＥ为三价稀土离子，Ｌ为西佛碱配体）．两种抗氧化实验都表明稀土配合物均具有优良的抗氧化作用，比配体本身的性能更佳 A sulfite thiazole and p-hydroxybenzaldehyde synthesis of a new West Fu alkali, and the ligand prepared eight kinds of rare earth complexes. The complexes were characterized by elemental analysis, IR, NMR, thermal analysis, molar conductance and dissolution properties. The complexes are composed of two types: REL (OH) 1.5H2O and REL (Cl) 1.5H2O (RE is a trivalent rare earth ion and L is a Schiff base ligand). Both antioxidant experiments have shown that rare earth complexes have excellent antioxidant activity, better than the ligand itself
