Use	disperse green C- 6B is used for dyeing and printing polyester and its blends. Deyan blue light is green. It is also used for color matching with other dyes. Excellent performance, can also be used for superfine fiber dyeing, especially for high temperature and high pressure dyeing, can also be used for Hot Melt dyeing and carrier dyeing.
production method	with 2-amino -3, 5-dinitrothiophene and M-acetamido-N,N-diethylaniline as raw material. The former is first diazotized and then coupled with the latter to obtain a product. The final product was obtained by filtration, grinding and drying.. 18g of sulfuric acid was added into the reaction flask, 0.027mol of NaNO2 was added under stirring, and the temperature was raised to 60 ℃. After the NaNO2 was completely dissolved and then cooled to 5 ℃, a mixture of 75g of acetic acid and 30g of propionic acid was added, continue to cool to 0 ℃, slowly add 2-amino -3, 5-dinitrothiophene 0.025mol, continue to react at 0 ℃ for 1H, add a small amount of urea, then react for 1H, diazo solution was obtained for standby use. Add 3.5g of hydrochloric acid, 30g of ice water and 0.025mol m-acetamido-N,N-diethylaniline to the reaction flask, stir to dissolve, cool to 0 ℃, slowly add the above diazo solution, and add it after 20min, stirring of the reaction was continued to the end point. The product was filtered, washed with water and dried.
