Process for the preparation of hydro-diphenyl amines |
| abstract |
The present invention relates to a process for the preparation of hydroxydiphenylamines by condensation of a dihydroxybenzene with an excess of a primary aromatic amine. This is carried out at elevated temperature in the presence of an acid and, following the reaction, the reaction mixture is worked up in the presence of a base by distillation. |
