Glacial acetic acid, also known as ethanoic acid, is a colorless liquid organic compound with a pungent smell and a distinctive sour taste. It is a key ingredient in various industrial processes and is also used in food preservation and cooking. The term glacial refers to its ability to form ice-like crystals at low temperatures; when cooled below 16.6 °C (62 °F), glacial acetic acid solidifies, resembling small ice crystals. This attribute is what sets glacial acetic acid apart from diluted acetic acid solutions commonly encountered, such as vinegar.

The corrosive properties of glacial acetic acid require special attention during both storage and handling. This substance can cause severe damage to metal surfaces and living tissues, making it critical to use corrosion-resistant materials in any equipment or containers that come into contact with the acid. In the workplace, personnel must be trained to recognize the signs of corrosion and take appropriate action, such as replacing or repairing affected equipment promptly. Additionally, safety measures, such as regular inspections and the use of protective coatings, can help mitigate the corrosive effects of glacial acetic acid on surfaces and equipment, ensuring a safer working environment.

In the laboratory, glacial acetic acid is widely employed as a solvent and reactant due to its properties as a weak acid. It is used in chemical synthesis, including the preparation of acetyl derivatives and other organic compounds. The control of the molecular mass is crucial when determining the proportions of reactants needed for successful synthesis.

In the food industry, glacial acetic acid is diluted to create vinegar, which has a range of culinary uses. Vinegar is widely used in food preservation, flavoring, and cooking. The acetic acid concentration in vinegar is typically around 5-20%, significantly less than in glacial acetic acid. This dilution ensures that vinegar can be safely consumed while still providing the beneficial properties of acetic acid.
