Reaction Steps
144 parts of α-naphthol, 143 parts of α-naphthylamine and 15 parts of triphenyl phosphite are mixed and heated to 220° C. The elimination of water commences at this temperature and has ended when the internal temperature reaches 250° C. 18 parts of water are removed in the course of 10 hours. After distilling off excess α-naphthol and α-naphthylamine, 250 parts of 1,1'-dinaphthylamine, of melting point 97° - 102° C, are obtained at 256° - 257°/5 mm Hg. This corresponds to a yield of 93% of theory.
