Reaction Steps
288 parts of α-naphthol, 205 parts of aniline and 15 parts of benzyl diethyl phosphite are mixed and heated to 200° C. The elimination of water commences at this temperature and has ended when the internal temperature is 235° C. 33 parts of water are removed in the course of 5 hours. After distilling off excess α-naphthol and aniline, 381 parts of phenyl-α-naphthylamine, boiling at 202° - 204° C/5 mm Hg. are obtained; the product has a melting point of 55° - 58° C and corresponds to a yield of 87% of theory.
