| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| use | disperse red 4 is a disperse dye. Bright pink or red powder. Concentrated sulfuric acid is orange and red, and precipitated after dilution. Transfer printing fabrics for polyester and its blends can also be used for dyeing and printing of cellulose fiber, triacetate fiber, polyamide fiber and acrylic acid, and can also be used for plastic shading. |
| production method | disperse red 4 can be brominated by 1-aminoanthraquinone first, then hydrolyzed in sulfuric acid medium, methoxylated with methanol in the presence of caustic soda, and then filtered, ground, dried and commercialized. |
