Anwendungen & Verwendung
Beschreibung
First produced in 1826 by Otto Unverdorben through destructive distillation of indigo, the first industrial use was as a purple dye, Mauveine, formulated by William Henry Perkin accidentally in an attempt to isolate quinone. The name aniline was given in deference to the indigoyielding plant, Indigofera suffruticosa, commonly named anil.
Verwenden
A thin, colorless oil prepared by reducing benzene with iron filings in the presence of hydrochloric or acetic acid and then separating the aniline formed by distillation. It is slightly soluble in water but dissolves easily in alcohol, ether, and benzene. Aniline is the base for many dyes used to increase the sensitivity of emulsions.
