The production process route of 2,6-dichloroaniline was compared, and it was proposed that aniline and urea were used as starting materials and condensed to obtain diphenylurea. Diphenylurea was sulfonated, chlorinated, hydrolyzed decarboacyl group and then hydrolyzed desulfonic acid group to obtain 2,6-dichloroaniline, with a total yield of 60% and a purity of more than 99%. Compared with the traditional process, the cost of 2,6-dichloroaniline synthesis is greatly reduced.
