Process for the preparation of N-di-n-propyl-2,6-dinitro-4-trifluoromethylaniline having a low content of nitrosamines |
| abstract |
N-di-n-propyl-2,6-dinitro-4-trifluoromethylaniline ("Trifluralin") with a low content in nitrosamines (less than 1 ppm) is prepared by reacting 4-trifluoro-2,6-dinitro-chlorobenzene with di-n-propylamine under the following critical conditions: n feeding to the chlorobenzoderivative the di-n-propylamine containing an alkali metal hydroxide or an alkaline carbonate so that the pH value of the reaction mass is comprised between 7 and 7.5; n regulating the temperature of the reaction mass so that it does not exceed 70° C.; and n operating in the presence of at least 50% by weight of water in the reaction mass. |
