Synthesis of n-phenyl-2-naphthylamine

Preparation of n-phenyl-2-naphthylamine

Preparation of n-phenyl-2-naphthylamine

Preparation of n-phenyl-2-naphthylamine

In a round-bottomed flask fitted with a thermometer and a vertical tube, a mixture of 143 grams (1.0 mole) of 1-naphthylamine, 175 grams of aniline, and 3 grams of sulfanilic acid is boiled vigorously for 42 hours. Ammonia is liberated and the boiling point of the mixture increases to 215°C. from an initial value of about 195°. When the reaction is completed, the mixture is fractionated carefully in the vacuum. Three fractions are taken: about 80 grams of aniline, about 10 grams of an intermediate fraction containing some aniline, a little 1-naphthylamine, and mainly n-phenyl-2-naphthylamine, and finally, 190 to 200 grams of n-phenyl-2-naphthylamine which solidifies at about 53°. The residue is discarded. At 12 mm. pressure, the boiling point of aniline is about 73°, of 1-naphthylamine about 160°, and of n-phenyl-2-naphthylamine about 224°.
