| titleOfInvention | A kind of preparation method of 2,6-dichlorodiphenylamine |
| abstract | The invention belongs to the technical field of chemical drug synthesis, and in particular relates to a preparation method of 2,6-dichlorodiphenylamine. The steps of the preparation method are as follows: (1) adding 2,6-dichloroaniline and a polar aprotic solvent to react In the bottle, after stirring and dissolving, add chlorobenzene, alkali and catalyst, stir and heat up to 120 ℃ ~ 160 ℃, and keep the reaction for 2h ~ 24h; the catalyst is nano copper oxide or nano cuprous iodide; (2) Step (1) The obtained reaction mixture is cooled to 50℃～90℃, filtered, and the filtrate is distilled under reduced pressure to obtain a crude product, and the crude product is purified to obtain 2,6-dichlorodiphenylamine. The method has high catalyst catalytic efficiency, less catalyst dosage, good reaction solvent selectivity and easy recovery, low raw material cost, high yield, high purity and high quality of the prepared product, and is easy to realize industrial production and application. |
