Disperse Orange S-4RL chemical properties:
Disperse Orange S-4RL is brown-red powder. Disperse Orange 30 is slightly soluble in ethanol, acetone, pyridine and DMF. When dyeing, copper and iron ions will affect the shade.
The production method of Disperse Orange S-4RL:
Disperse Orange S-4RL uses 2,6-dichloro-4-nitroaniline, acrylonitrile, ethylene oxide, and acetic anhydride as raw materials. First, aniline and acrylonitrile are cyanoethylated, and then with ethylene oxide Carry out hydroxyethylation, and finally esterify with acetic anhydride to obtain the coupling component; then diazotize 2,6-dichloro-4-nitroaniline, couple with the coupling component, filter, grind and dry to obtain the finished product Disperse Orange S-4RL.
