One of the primary uses of glacial acetic acid in the laboratory is as a solvent and reagent in organic synthesis. It is widely utilized for the production of various chemical compounds through esterification reactions, where acetic acid reacts with alcohols to form esters. For instance, the reaction of acetic acid with ethanol yields ethyl acetate, a common solvent used in many chemical processes. This feature makes glacial acetic acid an essential reagent for chemists working on synthesizing complex organic molecules and pharmaceuticals.

Both forms of acetic acid have widespread applications, though their uses differ significantly due to their concentrations. Regular acetic acid is commonly used in food products, especially as a preservative and flavoring agent. It is a key ingredient in pickling solutions and salad dressings. In contrast, glacial acetic acid has more specialized industrial applications. It serves as a crucial solvent in the production of various chemicals, including acetate, plasticizers, and synthetic fibers. It is also used in the manufacture of pharmaceuticals and as a reagent in laboratory settings.

The manufacturing of glacial acetic acid primarily involves two significant processes carbonylation of methanol and liquid-phase oxidation of naphtha. The most prominent method in modern production is carbonylation, in which methanol reacts with carbon monoxide in the presence of a catalyst to form acetic acid. This method is favored for its efficiency and the high purity of the resulting product, making it suitable for various applications.
