| Use | Disperse Blue 183 (Disperse Blue SE-2R) for dyeing and printing of polyester fabrics, is the main combination of dark dyes, can be with disperse Yellow SE-FL, disperse Red Jade SE-GFL composition of the three primary colors, can also be a separate dye blue. It can also be used to dye triacetate fiber, and the dyeing rate is not high, which is not suitable for dyeing other fibers. High lifting force, suitable for dyeing deep color, high temperature and high pressure dyeing method is suitable for light dye, color, uniformity, coverage is poor. With MELT Method dyeing, high lifting force, for polyester cotton blend, can be directly dyed and Bath dyeing step. suitable for polyester dyeing and ultra-fine printing. In addition to three vinegar fiber, not suitable for dyeing other fibers, dyeing three vinegar fiber, dyeing rate is not high. Can be used for direct printing of polyester fabric, light color can be used for discharge printing. |
| Performance | Disperse Blue 183 is an important disperse dye with excellent overall firmness, light resistance and sublimation resistance; the dyeing curve is flat, the coloring rate and the lifting force are very high, the color is bright, suitable for the dyeing of Ultrafine fibers, and the development prospect is good. |
| production method | M-propionamidoaniline was synthesized from M-Phenylenediamine and propionic acid in the presence of hydrochloric acid; then M-propionylamino-N,N-diethylaniline was synthesized from M-propionylaminoaniline and bromoethane in the presence of acid binding agent; finally, Disperse Blue 183 was synthesized by coupling reaction with the diazonium salt of 2-cyano-4-nitro-6-bromoaniline. Method 1: using p-nitroaniline and M-acetamido-N,N-diethylaniline as raw materials, P-nitroaniline was brominated, diazotized, and then coupled with M-acetamido-N,N-diethylaniline, the product was then obtained by cyanation. The final product was obtained by filtration, grinding and drying.. Method 2: 2-cyano-4-nitroaniline and M-acetamido-N,N-diethylaniline were used as raw materials, 2-cyano-4-nitroaniline was brominated and diazotized, the product is obtained by coupling with M-acetamido-N,N-diethylaniline. The final product was obtained by filtration, grinding and drying.. |
