실험 절차

144 parts of β-naphthol, 143 parts of α-naphthylamine and 10 parts of triphenyl phosphite are mixed. A homogeneous melt is formed at 120° C internal temperature. The elimination of water commences when the internal temperature reaches 230° C and has ended after 3 hours, at an internal temperature of 250° C. 18 parts of water have distilled off. 258 parts of 1,2'-dinaphthylamine, of melting point 106° - 108° C, are obtained by distillation at 239° C/0.1 mm Hg. This corresponds to a yield of 96% of theory.
