| Use | disperse red SE-R can be used for dyeing and direct printing of polyester fabric to obtain red with yellow light, high color, good levelness, moderate fastness, good stability to acid and alkali. Can be used as three primary colors, with Disperse Blue 2BLN and medium temperature type disperse dye dyeing a variety of light to medium color. It can also be dyed with polyester-viscose blended fabric, diacetate fiber and triacetate fiber. The color of dyed acrylic fiber is blue, and the dyeing rate is low, which can only be dyed in light color. |
| production method | with 2-chloro-4-nitroaniline and N-ethyl-N-cyanoethylaniline as raw materials, the product is obtained by first diazotization of 2-chloro-4-nitroaniline and coupling with N-ethyl-N-cyanoethylaniline. The final product was obtained by filtration, grinding and drying.. |
