| titleOfInvention | Preparation method of 3, 4-dichloronitrobenzene |
| abstract | The invention relates to a preparation method of 3, 4-dichloronitrobenzene. According to the method, chlorine gas is introduced into para-nitrochloro-benzene at 100 DEG C to 105 DEG C under the condition of anhydrous ferric chloride existence for taking chlorination reaction to obtain the 3, 4-dichloronitrobenzene. Particularly, the chlorination reaction is always carried out under the infrared microwave irradiation, after the chlorination reaction is completed, reaction materials are neutralized, washed and delaminated to obtain 3, 4-dichloronitrobenzene crude products, and the crude products are further rectified to obtain 3, 4-dichloronitrobenzene finished products. The yield of the target products 3, 4-dichloronitrobenzene obtained according to the method provide by the invention is improved, and the purity is improved. |
