Safety Data Sheet for Glacial Acetic Acid and Handling Guidelines

Zusammenfassend lässt sich sagen, dass die Herstellung von Gletscheressigsäure ein komplexer, aber gut etablierter Prozess ist, der in der modernen chemischen Industrie von großer Bedeutung ist. Dank kontinuierlicher Forschung und Entwicklung werden effizientere Methoden zur Herstellung und Reinheit von Essigsäure angestrebt, um den steigenden Anforderungen der Industrie gerecht zu werden.

The term glacial is derived from the appearance of the acid when it is cooled below its melting point (16.7°C), forming a solid mass akin to ice. Unlike household vinegar, which typically contains around 4-8% acetic acid, glacial acetic acid has a concentration of about 99.5-100%, making it significantly stronger and more reactive.

Understanding the Properties and Uses of Glacial Acetic Acid and Its CAS Number Identification

One such application is the synthesis of ethyl acetate, an important solvent and intermediate in organic synthesis. To prepare ethyl acetate, glacial acetic acid and ethanol are mixed together in the presence of an acid catalyst, usually concentrated sulfuric acid. The reaction involves the nucleophilic addition of ethanol to the carbonyl group of acetic acid, followed by the elimination of water to form ethyl acetate. This process is reversible, so excess ethanol is often used to drive the reaction forward.
