Heterocyclic quinazolinone-based hot brand monoazo reactive dyes were obtained by diazotization of 3-(4-aminophenyl)-2-phenylquinazolin-4(3H)-one and coupling with a variety of cyanurated coupling components. All the heterocyclic hot brand monoazo reactive dyes were characterized by elemental analysis (C, H, N) and by use of spectroscopic techniques (FT-IR, UV–visible, 1H NMR). Their performance as reactive dyes was assessed on silk, wool, and cotton fabrics. The dyes were found to give a variety of color shades with very good depth and uniformity on the fibers. The fastness of all the dyes on the fibers was moderate to excellent. Colorimetric data (L*, a*, b*, C*, H*, and K/S) of the synthesized dyes were also studied in detail.
基于杂环喹嗪啉酮的热品牌单偶氮反应性染料通过将3-(4-氨基苯基)-2-苯基喹嗪啉-4(3H)-酮进行重氮化反应,并与各种氰尿酸偶联组分进行偶联而获得。所有杂环热品牌单偶氮反应性染料均通过元素分析(C、H、N)和光谱技术(FT-IR、UV-可见光、1H NMR)进行了表征。其作为反应性染料在丝绸、羊毛和棉织物上的性能得到了评估。结果显示,这些染料在纤维上呈现出多种色调,且色彩深度和均匀性都非常好。所有染料在纤维上的耐光性从中等到优秀。合成染料的色度数据(L*、a*、b*、C*、H*和K/S)也进行了详细研究。
