摘　　要：以水杨醛、浓硫酸、碳酸钠与1,3-二氨基-2-丙醇为原料,采用2步法合成工艺制得双水杨醛磺酸钠缩二氨基-2-丙醇配体,再将配体与金属盐乙酸锰进行配位得到双核希夫碱金属锰配合物,红外光谱和能量色散X-射线能谱表征了配合物。将配合物应用于棉织物的低温漂白,探讨了配合物浓度、p H和乙酰胺用量对漂白效果的影响。结果表明,在配合物浓度为8μmol/L、p H为10.5～11.0、乙酰胺用量为8～9 g/L的条件下,处理后的棉织物白度达77.7%,毛细管效应达8.7 cm/30 min。Dual core Schiff base metal manganese complex was synthesized by two step process. Firstly, double salicylic aldehyde condensation diamino-2-hydroxypropane ligand was synthesized by salicylaldehyde, concentrated sulfuric acid, sodium carbonate and 1,3-diamino-2-hydroxypropane. Then, Schiff base metal manganese complex was obtained through the coordination of ligand and manganese acetate. The complex was characterization by infrared and EDS. The complex was applied in low temperature bleaching of cotton fabric and the effects of complex concentration, pH, acetamide dosage on the bleaching were discussed. The results showed that when the cotton fabric treated with 8 μmol/L Schiff base complex, 8-9 g/L acetamide, pH=10.5-11.0, the whiteness of treated cotton fabric reached 77.7%, capillary effect reached 8.7 cm/30 min.
