摘要
2-氨基-5-硝基苯酚重氮化后,分别与1-萘酚-4-磺酸和2-萘酚偶合,得到偶氮物Ⅰ和偶氮物Ⅱ;偶氮物Ⅰ和氧化铬铬化反应得到络合物Ⅲ;络合物Ⅲ再与偶氮物Ⅱ在碱性条件下反应得到蓝色不对称金属络合染料(C.I.酸性蓝317)。
2 - Amino -5 - nitrophenol was diazotized, then coupled with 2 - naphthol and 1 - naphthol -4 - sulfonic acid yielding azo compound Ⅰ and Ⅱ respectively. Azo compound Ⅰ reacted with chromium trioxide gaining metallined compound Ⅲ. The asymmetric met- alline dye C. I. Acid Blue 317 was obtained by the reaction of the compound Ⅲ with the compound Ⅱ in alkalic condition.
