分散蓝E-2BLN合成工艺研究

Investigation on Synthetic Technology of Disperse Blue E2BLN

分散蓝Ｅ－２ＢＬＮ为性能优良的分散染料．本文主要介绍对传统的二苯氧基化方法生产工艺中间的苯氧基化、硝化、溴化反应的改革方法和原理．

Disperse Blue E2BLN is a kind of dispersing dyestuff with excellent property. This paper describes the reasonably improved method and theory of phenoxylation, nitration and bromination reactions in traditional diphenoxylation process technology.
