- Preparation method of 3, 5-dichloroo-phenylenediamine
-
The invention relates to an industrial preparation method of 3, 5-dichloroo-phenylenediamine, which comprises the following steps of: by using 3, 5-dichloroaniline as an initial raw material, carryingout protection, nitrification, deprotection and reduction reaction to synthesize the 3, 5-dichloroo-phenylenediamine. The 3, 5-dichloroo-phenylenediamine obtained in the process is a brown solid, thepurity is 97.5%, the conversion rate of raw materials in each step reaches 100%, the total yield of the whole process reaches 52.7%, 3, 5-dichloroaniline is used as an initial raw material, the positioning property is good, the impurity is few, and the purification is easy.
