glacial acetic acid sigma aldrich_

Glacial acetic acid's freezing point is 16.6°C.

Glacial acetic acid, a colorless liquid organic compound, is known for its pungent smell and strong acidic properties. It is the pure, undiluted form of acetic acid, which is commonly used in various industries and laboratories. The significance of glacial acetic acid extends from its applications in production, research, and chemical processes to its classification in trade systems, specifically under the Harmonized System (HS) code.

Acetic acid, with the chemical formula CH3COOH, is a simple organic acid and a key component in vinegar. In its aqueous solution, it exists as a weak electrolyte, partially ionizing into acetate ions and hydrogen ions. However, when it comes to glacial acetic acid, the term 'glacial' is used to signify that it is virtually free from water, making it 100% pure. This high level of purity gives it a clear, colorless appearance, akin to ice, hence the term 'glacial'.

Glacial acetic acid, a colorless liquid with a strong, pungent odor, is a crucial chemical component in various industrial and laboratory processes. Its chemical formula is CH3COOH, and it is recognized as a non-fuming variety of acetic acid that is concentrated at 99% purity or higher. The term glacial refers to its ability to freeze at a temperature of around 16.6 degrees Celsius (62 degrees Fahrenheit), forming ice-like crystals that resemble glacial formations. This property not only reflects its physical state but also its significance in scientific and industrial contexts.

Despite the positive outlook, glacial acetic acid manufacturers face several challenges. Fluctuations in raw material prices, stringent environmental regulations, and competition from bio-based alternatives pose risks to profitability and sustainability. Moreover, the industry must navigate the complexities of global trade, especially in times of geopolitical tensions and supply chain disruptions.
