Summary:The industrial process of preparing halogenated carbonyl aniline with halogenated aniline and halogenated isocyanate as materials features the synthesis reaction at the temperature of 0-110 deg.c and in the presence of catalyst, which is organic acid-binding agent of triethylamine, pyridine or N, N-diethyl aniline and in the amount of 0.01-5.0 % of halogenated aniline. The industrial process has improved product crystal shape, improved effect of separating the product from the solvent, high production efficiency, high product yield and low production cost.
