Exploring the Properties and Applications of Glacial Acetic Acid from Sigma Aldrich

Acetic acid, commonly known as ethanoic acid, is a colorless liquid organic compound with a pungent smell and a sour taste. Its chemical formula is CH₃COOH, and it is a vital raw material and industrial chemical. One of its most distinctive forms is glacial acetic acid, which is essentially pure acetic acid. While the two terms are often used interchangeably in everyday conversation, they refer to different states and concentrations of the same compound. Understanding their differences is important for both scientific and practical applications.

What is Glacial Acetic Acid?

Is Glacial Acetic Acid Dangerous for Health and Safety Precautions to Consider

Glacial acetic acid has a melting point of approximately 16.6°C, which is why it is termed glacial, as it can form ice-like crystals at lower temperatures. Its boiling point is 118.1°C, and it has a flash point of 39°C, classifying it as a flammable liquid. The vapor can form explosive mixtures in air, presenting a significant fire hazard if not managed properly. In the event of a fire, glacial acetic acid can emit toxic fumes, including carbon monoxide and acetic anhydride.
