Before delving into the synthesis methods, it is essential to understand what glacial acetic acid is. The term glacial refers to its pure, concentrated form, which contains about 99% acetic acid. It differs from vinegar, which typically contains around 5-20% acetic acid, primarily being water. Glacial acetic acid is highly hygroscopic, meaning it can absorb water vapor from the air, making it essential to store it in airtight containers.

The applications of glacial acetic acid and dilute acetic acid vary significantly due to their differing concentrations and properties. Glacial acetic acid is primarily used in industrial settings. It serves as a crucial raw material in the production of various chemicals, such as acetate esters, acetic anhydride, and acetic acid derivatives. Industries such as textiles, plastics, and food processing utilize glacial acetic acid for synthesizing fibers, films, and other chemical products.

The name “glacial” has historical roots. The term was coined by chemists in the 19th century when they recognized that the pure form of acetic acid looked similar to ice or glaciers when it solidified. Furthermore, scientists noticed that when this concentrated acetic acid was cooled sufficiently, it would crystallize, leading to the visual association with frozen water or glacial ice. This terminology not only captures the visual element but also hints at the high purity level of the substance that is vastly different from diluted acetic acid used in household products.
