2,7-Naphthalenedisulfonic acid, 4,4′-[carbonylbis[imino(5-methoxy-2-methyl-4,1-phenylene)-2,1-diazenediyl]]bis[5-hydroxy-, sodium salt (1:4) Use and Manufacturing
Taking H acid, Clixidin and phosgene as raw materials, first diazotizing H acid, then coupling with Clixidin, and then condensing with one molecule of phosgene with two molecules of coupling product to obtain the product. After salting out, filtering, drying and crushing, the finished product is obtained.
Direct light fast red 4BL is used for dyeing cotton and viscose fiber fabrics. It has good dyeing rate and slightly poor migration and level dyeing properties. It is also used for direct printing of cotton and viscose fiber fabrics, ground color white-out printing, and printing on silk and wool fabrics. It can also be used for dyeing polyester-viscose blended fabrics with disperse dyes in the same bath as well as for coloring leather, paper and anodized aluminum.
