The main purpose
Dye intermediates. It is mainly used to produce disperse dyes, such as disperse yellow brown 3GL, disperse yellow brown 2RFL, disperse brown 3R, disperse orange s-4rl, disperse blue s-bbl, disperse yellow brown se-4br, disperse yellow brown h-2rl, colorant 0-11 and so on.
The synthetic methods
There are mainly the following methods: p-nitroaniline chlorination in hydrochloric acid - glacial acetic acid; Chlorination of 2-sulfonic acid - 4-nitroaniline; P-nitroaniline is chlorinated in dilute hydrochloric acid and sodium hypochlorite. P-nitroaniline reacts in hydrogen peroxide and hydrochloric acid; P-nitroaniline was sulfonated and then chlorinated in concentrated sulfuric acid. P-nitroaniline reacts with sodium chlorate in concentrated hydrochloric acid.
