Glacial acetic acid serves a variety of critical functions across different industries. One of its most notable uses is in the production of chemical intermediates, such as acetic anhydride and acetate esters. Acetic anhydride, for instance, is important in the manufacture of various pharmaceuticals and dyes. Meanwhile, acetate esters are widely utilized as solvents in the coatings and adhesives industries. Furthermore, glacial acetic acid is a key ingredient in the production of vinegar, where it is diluted to create the familiar condiment. In industrial settings, it is often employed for pH control and as a dehydrating agent in the synthesis of other chemicals.

Glacial acetic acid has a distinct pungent odor and a very high boiling point of approximately 118.1°C (244.6°F). Its molecular structure consists of a carboxylic acid functional group (-COOH), contributing to its acidic properties. The acidity of glacial acetic acid is significantly stronger than that of its diluted counterpart; its pKa value is around 4.76. This characteristic allows it to be an effective solvent and reagent in various chemical reactions, especially in organic chemistry.

Before delving into the production methods, it is essential to understand the historical context of acetic acid. Acetic acid has been known since ancient times, being derived relatively simply through the fermentation of sugars and carbohydrates. However, for industrial applications, the need for a purer and concentrated form emerged, leading to the development of synthetic methods.
