| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Use | It is used as an intermediate for disperse dyes to prepare disperse cyan 2GL dye intermediate. Used for the production of dispersed cyan 2GL. |
| production method | obtained by reacting 2, 4-dinitroaniline with bromine: add 1800L of water to 300L glass-lining reaction pot, 300kg of 2, 4-dinitroaniline, 100kg of hydrochloric acid and 3kg of chlorinated benzene were stirred for 1H. 180kg of bromine was added at room temperature and reacted at 50-55 ° C. For 6H. Then slowly add sodium hypochlorite (equivalent to 100% available chlorine 33.5), insulation 3H. After reaching the end point, add sodium sulfite aqueous solution (fold 100% 25-30kg), eliminate the remaining bromine, filter wash to neutral, dry to get the finished product. Industrial products are orange crystals, the content is greater than or equal to 98%, the melting point is greater than or equal to 148. Raw material consumption quota: 2, 4-dinitroaniline 770kg/t, bromine 600kg/t. |
