PROCESS FOR THE PREPARATION OF 6-BROMO-2,4-DINITROANILINE

摘要

A process for preparing 6-bromo-2,4-dinitroaniline of formlula (I) comprises a reaction of 2,4-dinitroaniline of formula (II) and Br2 in the presence of a dispersing agent and CH3COOOH. Pref. the weight ratio of the dispersing agne tto 2,4-dinitroaniline is 0.05-1.0 wt.%. (I) is useful as an intermediate in the manufacture of dispersing dyes.
