a-Naphthylamine is an aromatic amine derived from naphthalene.It crystallizes in colorless needles which melt at 50 °C.It possesses a disagreeable odor, sublimes readily, and turns brown on exposure to air.a-Naphthylamine is the precursor to a variety of dyes.It can be prepared by reducing 1-nitronaphthalene with iron and hydrochloric acid at about 70 °C. After the reaction mixture is neutralized with milk of lime, the naphthylamine steam-distilled.a-Naphthylamine can also be prepared, in the form of its acetyl derivative, by heating 1-naphthol with sodium acetate, ammonium chloride and acetic acid; by heating 1-naphthol with calcium chloride-ammonia to 270 °C; and by heating pyromucic acid, aniline, zinc chloride and lime to 300 °C.
