Acetonitril

Beschreibung:

Acetonitril, mit der chemischen Formel CH₃CN und der CAS-Nummer 75-05-8, ist eine farblose, flüchtige Flüssigkeit, die weit verbreitet als Lösungsmittel in verschiedenen chemischen Prozessen verwendet wird. Sie hat einen charakteristischen süßen Geruch und ist hochpolar, was sie zu einem ausgezeichneten Lösungsmittel für eine Vielzahl organischer Verbindungen macht, insbesondere in Reaktionen mit Nucleophilen. Acetonitril hat einen relativ niedrigen Siedepunkt und eine hohe dielektrische Konstante, was zu ihrer Wirksamkeit beim Lösen von Salzen und anderen polaren Substanzen beiträgt. Sie ist mit Wasser und vielen organischen Lösungsmitteln mischbar, was ihre Nützlichkeit in Labor- und Industrieanwendungen erhöht. Acetonitril wird auch in der Herstellung von Arzneimitteln sowie bei der Extraktion bestimmter Verbindungen und in chromatographischen Techniken verwendet. Obwohl sie allgemein als wenig giftig gilt, kann eine Exposition zu Haut-, Augen- und Atemwegsreizungen führen, was angemessene Sicherheitsmaßnahmen beim Umgang erforderlich macht. Ihre chemische Stabilität und Reaktivität machen sie zu einer wertvollen Verbindung in der organischen Synthese und der analytischen Chemie.
