摘要
乙二胺二邻苯基乙酸钠EDDHA-Na无磷环保,在碱性条件下对过渡金属离子螯合作用强,并具有优异的分散性能,既能有效抑制漂白工作液中的Mn^(2+)、Cu^(2+)、Fe^(3+)对过氧化氢的过度激活,避免产生布面黄斑与氧漂破洞,也能悬浮织物在漂白过程中脱落的各种杂质,防止污垢沉积于织物表面,导致织物色光暗淡和手感粗糙。以氯乙酸、乙二胺、癸酰氯为原料,合成EDDHA-Na,测试产物的螯合与分散性能,并与MgSO_(4)共同应用于棉织物漂白工艺,试验结果表明EDDHA-Na和MgSO_(4)以质量比5∶1复配可以获得最佳的漂白效果。
EDDHA-Na has strong chelating ability on heavy metal ions under alkaline conditions and the excellent dispersion properties,which is environmentally friendly.It can not only effectively inhibit the Mn^(2+),Cu^(2+),Fe^(3+)activoting hydrogen peroxide in the bleaching solution,avoid the generation of yellow spots and the holes by oxygen bleaching on the fabric surface,but also disperse the various impurities which fall off during the bleaching process.EDDHA-Na can prevent the deposition of dirt on the surface of the fabric,which can lead to the gray color and coarseness of fabric.EDDHA-Na was synthesized from ethylenediamine,chloroacetic acid and decyl chloride.The chelating and dispersing properties were tested.The results showed that the best bleaching effect could be obtained by adding EDDHA-Na and magnesium sulfate with the ratio as 5:1.
