Aniline → N-phenyl-2-naphthylamine

Participants

Reaction Conditions

Reaction Steps

288 parts of β-naphthol, 220 parts of aniline and 5 parts of phosphorous acid are mixed and heated to 173° C. At this temperature, the elimination of water commences. The reaction temperature rises to 230° C in the course of 4 hours. At that stage, the reaction has ended and 36 parts of water have been removed. The further working up is carried out as described in Example 8. 412 parts of N-phenyl-β-naphthylamine of melting point 100° - 102° C are obtained, corresponding to a yield of 94% of theory.
