Product Applications of Acetic Acid
Acetic acid is a key industrial chemical widely used in the production of vinyl acetate, acetic anhydride, acetates, and cellulose acetate. These derivatives are essential in the manufacture of adhesives, films, synthetic fibers, rayon, and photographic materials.
Its esters serve as high-quality solvents for coatings, paints, and inks, while acetic acid itself is used as a solvent and reaction medium in oxidation processes and PET plastic production. In organic synthesis, it is an important raw material for pharmaceuticals, agrochemicals, and chemical intermediates.
Acetic acid is also applied in the preparation of metal acetates for textile, leather, and medical uses, and in the food industry as an acidifier, flavor enhancer, and seasoning agent. Due to its corrosive nature, proper safety handling is required.
