一种Schiff碱铜配合物对双氧水漂白的催化作用

水杨醛与牛璜酸以1∶1的比例在无水乙醇中反应,生成水杨醛缩牛璜酸席夫碱,再与C u（Ⅱ）金属离子络合,合成Schiff碱铜配合物,用红外光谱证实了其结构。通过＂正交试验法＂研究了该配合物对双氧水漂白棉织物的催化作用。实验对漂白后的棉织物的断裂强度、白度等指标进行了测试及分析,结果表明,该配合物对双氧水漂白有较好的催化作用。当配合物的浓度为0.4 g/L,pH=9,温度为60℃,时间为60 m in,此时棉织物的白度和断裂强度较好。

The Catalysis of a Schiff Base Copper Complex for the Bleaching of Hydrogen Dioxide

Taurine - salicylic Schiff base was synthesized from salicyladehyde and taurine （ 1：1 ）in the solution of alcohol, then its Cu complex was made from the Schiff base and Cu（ Ⅱ ） ,structure of the complex was verified by IR. In orthogonal experimenta- tion,the influences of H202 bleaching by the complex in different condition were investigated. The white content and break strength of bleached fabric were tested and analyzed. The results showed that this Cu complex could quickly catalyze H2O2 bleaching. By 0.4 g/L complex at 30 ℃ and pH = 9, hold 60 min, the white content and break strength of cotton fabric are better.
