提高取代蒽醌收率的合成工艺研究

Improvement on Yield of the Synthesis for Substiuting Anthraguinone

以苯酐和取代苯为原料,经过乙酰化、水解及环合反应,合成了2-氯蒽醌和2-氨基蒽醌,并对影响收率的工艺条件进行了研究。实验表明:采用优化反应条件,所得产品总收率在82％以上(以苯酐计)。

In this paper, the synthesis of 2 - chloranthraquinone and 2 - aminoanthraquinone was studied. It was prepared from phthalic anhydride by acetyiation, hydrolysis and cyclization. A total yield of 82% was obtained.
