The Synthetic Process of Disperse Peach SE-RL

Abstract:

Article Preview

Based on 1-amino-4-hydroxy-2-phenoxy anthraquinone (Disperse Red FB) and ethylene glycol phenyl ether as raw materials, polyethylene glycol (PEG) as catalyst, condensation in alkaline conditions. The optimum reaction temperature is about 140°C, 4 h reaction times, 9g catalyst, the ratio of recovery and fresh consumptions of ethylene glycol phenyl ether is controlled in 1:1 (ml). The reaction end point is easy to arrive in these conditions, and the yield of disperse peach SE-RL (Disperse Red 191) is the best, about 79.2%.
