有机颜料橙74的合成与应用研究

Research on Synthesis and Application of Organic Pigment Orange 74

以4-胺基-2，5-二氯-N，N-二甲基-苯磺酰胺以及萘酚AS—E（4-氯-3-羟基-2-萘甲酰苯胺）为起始原料经过重氮化，偶合以及后处理过程得到新的颜料，并对该颜料的应用性能进行了测试。

The passage introduces a new kind of pigment which was obtained by diazotization, coupling and post-treatment of 4--amino--2, 5--dichloro--N, N--dimethyl--benzenesulfonamide and naphthol AS-E （i.e. 4-- chloro, 3- hydroxyl--2- napthanilide ） . Tests of its application performance are also reported.
