글루시어 아세트산(NFPA) - 안전 데이터 및 위험도 정보

Glacial acetic acid is the pure form of acetic acid, containing at least 99% acetic acid by volume. It has a melting point of 16.6 °C, meaning it will solidify at lower temperatures, which is why it is referred to as glacial. It acts as a weak acid but is highly soluble in water, forming a colorless solution. Due to its strong acidity and corrosive nature, handling glacial acetic acid requires caution.

One of the most common uses of glacial acetic acid is as a solvent in chemical reactions. Its ability to dissolve a wide variety of substances makes it an invaluable resource in laboratories for synthesizing different chemical compounds. It serves as a key reagent in the production of various chemicals, including acetate esters, which are used in the manufacturing of plastics, fibers, and other consumer goods. The production of acetic anhydride, another essential chemical compound, also relies on the use of glacial acetic acid.

Glacial acetic acid has the chemical formula CH₃COOH, which denotes a simple carboxylic acid structure consisting of a methyl group (CH₃) attached to a carboxyl group (COOH). Its molecular weight is approximately 60.05 g/mol. This compound possesses a strong, pungent odor and has a sour taste, reminiscent of vinegar, from which it is derived. In addition to being a strong acid, it can act as a solvent and is miscible with water in all proportions, meaning that it can dissolve at any ratio.

NFPA Hazard Classification for Glacial Acetic Acid and Its Safety Considerations

Glacial acetic acid, known for its purity and high concentration, is a vital compound that finds extensive applications in various fields, including industrial, laboratory, and even culinary contexts. When available in powder form, it compounds its usability and versatility, making it a significant substance for researchers, manufacturers, and even food enthusiasts.
