【Abstract】 The methord of synthesis of salicylaldehyde amino acid Schiff base and its rare earth complexes was studied, and the effect of factors such as the pH and solvent, on the reaction system was discussed, too. The results show that, in the methord of step by step synthesis, synthesizing ligands by controlling the pH in the range of 7～7.5 and synthesizing complexes by controlling the pH in the range of 6.5～7 with anhydrous ethanol as solvent, may contain ideal amino acid Schiff base and its rare earth complexes.更多还原
