2-磺酸基-4-β-硫酸酯乙基砜基苯胺是KN型染料的重要中间体,KN型染料具有较高的耐酸性水解能力和独特的应用性能,应用范围广,是色谱齐全、品种繁多的一大类活性染料。在染料索引中的各类活性染料中,其数量仅次于一氯均三嗪染料,居第二位。2-磺酸基- 4-β-硫酸酯乙基砜基苯胺属KN型染料的重氮类,由于KN型染料染色时所形成的活性物质乙烯砜水溶性较小,如果偶合组分的溶解度也较小,则需在含活性基的重氮组分中引入磺酸基以增加整个染料分子的溶解度,从而提高染料的性能。2-磺酸基-4-β-硫酸酯乙基砜基苯胺的纯度对合成染料的色光等因素影响很大,本文对4-β-硫酸酯乙基砜基苯胺的磺化进行了详细的研究。
2-sulfo-4-β-sulfate ethyl sulfone Aniline is an important intermediate KN dye, KN dye with high acid hydrolysis ability and unique application performance, wide range of applications, is the chromatographic complete , A wide variety of a large class of reactive dyes. In the dye index of various types of reactive dyes, the second only to the number of chloro-triazine dye. 2-sulfonate - 4-β-Sulfate ethyl sulfone Aniline KN dye diazo, because KN dye dyed active substance formed when the vinyl sulfone water solubility is small, if the coupling component solubility Also smaller, you need to introduce reactive groups in the diazo component sulfonic acid group to increase the solubility of the entire dye molecules, thereby enhancing the performance of the dye. The purity of 2-sulfo-4-β-sulfoethyl sulfone aniline greatly affects the color of the synthetic dyes and other factors. In this paper, the sulfonation of 4-β-sulfoethyl sulfone aniline was detailed the study.
