105635-65-2 - Reference Information
| Use | dyeing of polyester and its blended fabrics under high temperature and high pressure and carrier method dyeing of polyester and its blended fabrics with Disperse Blue S-3GL and direct dyeing of polyester fabrics printing, dyeing depth is good, levelness is poor, is the main dye dark blue. It can be mixed with disperse Yellow Brown H2RL, disperse Hongyu 2GFL, disperse red HBGL, and has good compatibility. Also can be dyed acetate fiber. |
| production method | with 2, 4-dinitro-6-bromoaniline as the diazo component, the product is obtained by coupling diazotization with the coupling component N,N-bis (methoxyethylamino)-2-methoxy-5-acetylaminobenzene. The final product was obtained by filtration, grinding and drying. There are two methods for the synthesis of the coupling components. Method 1: p-nitrochlorobenzene method.. Method 2:2, 4-dinitrochlorobenzene method.. Finally, the diazo component is diazotized and coupled with the coupling component to obtain the product.. |
