摘要
用2-氨基苯酚-4-磺酸重氮化,与邻羧基二苯腙进行偶合,然后铜化得到新结构的蓝染料。该染料的各项应用性能达到或超过酸性蓝168,特别是溶解度提高5倍。本文介绍了新染料的化学结构及合成方法。
Acid Blue 2BNL was synthesized by diazotization of the sodium salt of 2-amino phenol-4-sulfonic acid followed by coupling with o-carboxy-diphenylhydrazone, then metallization with copper sulphate. The dyeing properties of it were as good as or even better than that of C.I. Acid Blue 168, particularly the solubility of which was up to five times better than the latter.
