Die glaziale Essigsäure hingegen ist der reine, wasserfreie Zustand der Essigsäure. Sie enthält weit über 99% Essigsäure und wird als „glazial“ bezeichnet, weil sie bei Raumtemperatur und unter Normaldruck ohne Wasser vorliegt. Glaziale Essigsäure ist ein farbloses, viskoses Flüssigkeit, das bei 16,6 °C gefriert und dann eine kristalline Struktur annimmt. Aufgrund ihrer hohen Reinheit und Dichte wird glaziale Essigsäure häufig in der chemischen Synthese verwendet.

Despite its many applications, handling anhydrous acetic acid requires caution due to its corrosive nature. It can cause severe burns upon contact with skin and eyes, and inhalation of vapors can irritate the respiratory tract. Therefore, proper safety measures, such as the use of personal protective equipment (PPE) and adequate ventilation in workspaces, are essential when dealing with this chemical. The storage of anhydrous acetic acid must comply with environmental regulations to prevent spills and emissions, as it can pose risks to aquatic life and ecosystems.

Vinegar is a versatile ingredient widely used in culinary applications, preservation, and even cleaning. While most people may associate vinegar with fermentation and the traditional process of brewing wine or cider, it's also possible to create vinegar using glacial acetic acid. This process involves diluting the concentrated acid with water and fermenting the resulting solution. Understanding the steps involved can help you produce high-quality vinegar safely and effectively.
