Product Application
Acetic acid is a large-scale industrial chemical and one of the most critical organic acids in the chemical industry. Its main applications include producing vinyl acetate, acetic anhydride, various acetates, and cellulose acetate. Vinyl acetate serves as a precursor to polyvinyl acetate—used in adhesives, films, and as a raw material for the synthetic fiber vinylon—while cellulose acetate is commonly employed in manufacturing rayon and photographic film.
Esters formed by acetic acid and lower alcohols are excellent solvents, widely used in the coatings and paints industry. Additionally, acetic acid acts as a solvent in oxidation reactions, such as the oxidation of p-xylene to terephthalic acid—a key precursor to PET plastics.
In organic synthesis, acetic acid is essential for producing acetic anhydride, diethyl malonate, ethyl acetoacetate, halogenated acetic acids, as well as pharmaceutical intermediates (e.g., aspirin) and agrochemicals (e.g., 2,4-D herbicide).
Acetic acid also contributes to manufacturing metal acetates (e.g., sodium, manganese, lead, aluminum, zinc, and cobalt salts). These compounds function as catalysts or additives in industries like textile dyeing and leather tanning. For example, aluminum acetate is used as a mordant and medical disinfectant; lead acetate is a traditional pigment called white lead; and lead tetraacetate is an oxidizing reagent in organic synthesis—particularly for converting 1,2-diols into aldehydes or ketones. Sodium acetate and potassium acetate are common buffering agents in biochemical applications.
In the food industry, acetic acid is utilized as an acidifier, flavor enhancer, and seasoning. For synthetic vinegar production, it is diluted to a 4–5% concentration and blended with flavorings to mimic traditional vinegar—an economical and time-efficient method.
Notably, acetic acid is highly corrosive, capable of causing skin irritation and blistering. Classified as a Category 2 corrosive organic acid, it must be handled with appropriate safety precautions.
