| Utilisation | 3-chloro-4-methylnitrobenzene is an intermediate of the herbicide chlorotoluron. Organic synthesis intermediates. Used to produce green tamarone. Used as a raw material for medicine |
| Méthode de production | It is obtained by chlorination of p-nitrotoluene. First, add dry pure p-nitrotoluene to the acid-resistant ceramic three-mouth bottle, heat it to 55 ℃ in an external water bath, then add a small amount of iodine and iron filings, and enter chlorine at 50-60 ℃. After a few hours, the chlorine absorption will stop when the theoretical amount is reached. At this time, reactants are precipitated in the bottle, and the reactants are heated by steam to melt and then extracted, and washed twice with 5% dilute hydrochloric acid. Then wash once with 1% sodium carbonate solution, and finally wash once with hot water, stir the oil into cold water to form granules, filter, wash with cold water, and blow dry at 40 ℃ to obtain the finished product. In industrial production, the operation process can be carried out in a dry reaction pot. The molten nitrotoluene is put into the reaction pot, iron wire and iodine tablets (or ferric chloride) are added, and an equal molar amount of chlorine is introduced at 58-62 ℃. After being washed with hot water and neutralized with sodium carbonate, it is poured into ice water, stirred to precipitate crystals, filtered, and dried in the shade to obtain the finished product. the preparation method is to add p-nitrotoluene into the reaction kettle, then add the catalyst anhydrous ferric chloride and iodine, under stirring, raise the temperature of the reaction material to 55~70 ℃, pass chlorine gas for reaction, take samples and track and analyze by gas chromatography, reach the end point, stop passing chlorine gas, keep the temperature for 1h, then wash with water, let it stand and delaminate to obtain 3-chloro -4-methylnitrobenzene, and crystallize to obtain the finished product. |
