Reaction Steps
288 parts of α-naphthol, 205 parts of aniline and 10 parts of dibenzyl phosphite are mixed and heated to 195° 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 4 hours. After distilling off excess α-naphthol and aniline, 374 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 85% of theory.
