ABSTRACT:
Hydroxy aromatics are aminated to form the corresponding aromatic amine by reaction at 200.degree.-400.degree.C with ammonia in the presence of a cyclohexanone and water in contact with a hydrogen transfer catalyst. For example, 2,6-dimethylphenol reacts with ammonia in the presence of cyclohexanone, water and a supported palladium catalyst to form 2,6-dimethylaniline.
