| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| use | disperse blue BBLS is used for dyeing polyester and its blended fabrics, with bright color, high lifting power and good sun and sublimation fastness. It can be used for dyeing triacetate fiber and acrylic fiber, as well as direct printing of polyester and triacetate fiber fabrics, not for dyeing diacetate fiber and nylon. |
| Production method | Using 2, 6-dibromo (or chlorine)-4-nitroaniline and m-acetamido-N,N-diethylaniline as raw materials, first 2, 6-dibromo (or chlorine)-4-nitroaniline diazotized, and then coupled with m-acetamido-N,N-diethylaniline, the product is then cyanated with cuprous cyanide. The finished product is filtered, ground and dried.. |
