还原黑DB染料的合成新进展

Synthesis of New Progress in Reduction of Black DB Dye

还原黑DB是以紫蒽酮作为骨架的黑色还原染料,通过紫蒽酮硝化制得,它原系绿色,经氧化后成为黑色,作为黑色还原染料应用,主要用于棉织物染色,还可以用于黏胶、丝绸和羊毛等的染色。通过几种合成实验线路的对比,寻求最佳合成线路,以进行工业化生产。

Reduction of black DB is the purple anthrone as skeleton black vat dyes, prepared by the the purple anthrone nitrification, it is green,after oxidation into blake, as the application of vat dye black, mainly used for cotton fabric dyeing, can also be used for viscose, dyeing of silk and wool etc. Through the comparison of several synthetic experiment circuit, to seek the best synthetic, to carry out industrial production.
