Glacial Acetic Acid Properties, Uses, and Availability
Glacial acetic acid, a colorless liquid with a pungent odor, is a vital chemical compound that plays a fundamental role in various industrial applications. Its chemical formula is CH₃COOH, and it is a concentrated form of acetic acid, containing around 99% of acetic acid by weight. The term glacial refers to its solidification at low temperatures, where it forms crystals resembling ice. This unique characteristic, along with its versatile uses, makes glacial acetic acid essential for numerous sectors, from manufacturing to food processing.
Properties of Glacial Acetic Acid
Glacial acetic acid is known for its high acidity and strong corrosive nature. It has a boiling point of 118.1 °C (244.6 °F) and a melting point of 16.6 °C (61.88 °F), which allows it to remain liquid at room temperature. In addition to its industrial importance, it is also a common laboratory reagent used in chemical synthesis and various analytical purposes. Due to its hygroscopic nature, it readily absorbs moisture from the air, which contributes to its effectiveness as a dehydrating agent.
