摘要
4-氨基-3-羟基-1-萘磺酸重氮化,与1-苯基-3-甲基-5-吡唑啉酮偶合,得单偶氮染料,后用Al2(SO4)3或Fe2(SO4)3在60℃～90℃进行络合反应3-5小时,得标题染料。用IR、UV对染料进行了分析和表征,Fe、Al、Cr络合染料的最大可见吸收光谱分别勾473、493、510nm,染色实验结果表明,所合成的染料在羊毛上染色有较好的应用性能。
4-Amino-3-hydroxynaphthalene-1-sulfuric acid was diazotized, then coupled with 1-phenyl-3-methyl-5-pyrazolone, gave a monoazo dye, which was complexed with Al2(SO4)3 or Fe2(SO4)3 at 60-90℃ for 3-5 hours to give the title dyes. These dyes were characterized by IR, UV and fluorescence spectra, the maximum absorption of the Fe, Al and Cr complex dyes were at 473nm, 493nm, and 510nm respectively. The dyeing result showed that the synthesized dyes had good application properties on wool
