某些蒽醌吡酮（ ）衍生物在染料工业中作为分散染料及酸性染料，应用于 合成纤维及动物纤维的染色。我们研究了利用二乙烯酮合成蒽醌吡酮衍生物的方法，在进行 ４－澳基３’－乙酰基Ｎ－甲基蒽醌吡酮的芳胺化反应时，发现了在芳胺化的同时，吡酮环上乙酰 基发生脱裂的反应。并证实了脱酰基反应是在高温下和酸性物质存在下发生的；芳胺化过程 中放出的澳化氢为引起脱酰化反应的原因。将乙酰基蒽醌吡酮衍生物与稀盐酸一起放在密封 玻璃管内加热，即能发生脱酰化反应。
Certain anthraquinone pyrazolone derivatives are used as disperse dyes and acid dyes in the dye industry for the dyeing of synthetic and animal fibers. We have studied the use of diketene synthetic anthraquinone pyrone derivatives, 4-a-3-acetyl-N-methylanthraquinone anthonyquinolone arylation reaction was found in the arylamine At the same time, acetylation of pyrazinone ring occurred cracking reaction. It was confirmed that the deacylation reaction occurred at high temperature and in the presence of acidic substances. O-hydrogen released during the arylation process was responsible for the deacylation reaction. The acetylanthraquinone pyrazolone derivatives and dilute hydrochloric acid together in sealed glass tube heating, that can occur deacylation reaction.
