Reaction Steps

288 parts of α-naphthol, 205 parts of aniline and 10 parts of diethyl phosphite are mixed and heated to 196° C. The elimination of water commences at this temperature and has ended when the internal temperature is 234° C. 27 parts of water are removed in the course of 8 hours. After distilling off excess α-naphthol and aniline, 330 parts of phenyl-α-naphthylamine are obtained at a boiling point of 203° - 205° C/5 mm Hg; the product has a melting point of 54° - 58° C and corresponds to a yield of 75% of theory.
