WAS BEDEUTET QUINOLINE AUF ENGLISCH
Quinoline
Chinolin ist eine heterocyclische aromatische organische Verbindung mit der chemischen Formel C9H7N. Es ist eine farblose hygroskopische Flüssigkeit mit einem starken Geruch. Gealterte Proben, wenn sie dem Licht ausgesetzt sind, werden gelb und später braun. Chinolin ist in kaltem Wasser nur wenig löslich, löst sich aber leicht in heißem Wasser und den meisten organischen Lösungsmitteln auf. Quinoline selbst hat nur wenige Anwendungen, aber viele seiner Derivate sind in verschiedenen Anwendungen nützlich. Ein prominentes Beispiel ist Chinin, das natürlich in Pflanzen als Alkaloide gefunden wird. 4-Hydroxy-2-alkylchinoline sind an der Antibiotikaresistenz beteiligt.

Quinoline is a high-boiling liquid; isoquinoline is a low-melting solid; each has a
sweetish odour. Both bases have been known for a long time: quinoline was first
isolated from coal tar in 1834, isoquinoline from the same source in 1885.
