Use | Disperse Blue RD is used for dyeing and printing of polyester and its blended fabrics to obtain red and blue colors. Suitable for high temperature and high pressure dyeing and carrier dyeing. |
production method | 2-amino-5-nitrothiazole and 3-methyl-N-ethyl-N-Hydroxyethyl aniline are used as starting materials. 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.. |
