Reaction Steps
144 parts of α-naphthol, 150 parts of aniline and 5 parts of triphenylphosphite are mixed and first heated to 180° C. The reaction commences, with elimination of water. The water is removed by means of a water separator and the aniline evolved is returned. The temperature rises to 210° in the course of 4 hours. After a further 4 hours at 212° C, the elimination of water has ended (18 parts of H2O). The reaction mixture is cooled to 150° C and the excess aniline is distilled off under reduced pressure. Thereafter, 208 parts of phenyl-α-naphthylamine distil at 202° - 203° C/5 mm Hg; this product has a melting point of 55° - 58° C and corresponds to a yield of 95% of theory.
