|Section2= |Section3= |Section4= }} 1-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. It is the precursor to a variety of dyes.〔Gerald Booth "Naphthalene Derivatives" in Ullmann's Encyclopedia of Industrial Chemistry, 2005, Wiley-VCH, Weinheim. .〕 ==Preparation== 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. It 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「1-Naphthylamine」の詳細全文を読む スポンサード リンク
