| titleOfInvention | Controlled feed process for making 3, 5-diaminobenzotrifluoride |
| abstract | Disclosed is a method of making 3,5-diaminobenzotrifluoride from 4-chloro-3,5-dinitrobenzotrifluoride. A solution of 4-chloro-3,5-dinitrobenzotrifluoride in an alcohol is prepared. Separately, a slurry is prepared of a palladium catalyst on a suitable substrate, at least one equivalent of magnesium oxide per equivalent of 4-chloro-3,5-dinitrobenzotrifluoride, sufficient hydrogen-donating reducing agent to reduce the 4-chloro-3,5-dinitrobenzotrifluoride to 3,5-diaminobenzotrifluoride, and an amount of alcohol sufficient to make the slurry stirrable. The solution is added to the slurry with stirring at a rate that does not exceed the reaction rate of the 4-chloro-3,5-dinitrobenzotrifluoride so that no unreacted 4-chloro-3,5-dinitrobenzotrifluoride accumulates in the slurry. The reaction mixture is heated at about 75 DEG to about 100 DEG C. |
