About Acetic Acid. Acetic Acid (a.k.a. Ethanoic Acid, Hydrogen Acetate, Vinegar) is an organic compound, in the carboxylic acids class. It is a clear, colorless liquid, with sharp odor and burning taste, miscible with water and most organic solvents. It can be found naturally in dilute solutions in plants and animal systems, as well as in ocean water, rain and oilfield brines. Its existence has been known for more than 2,000 years, and, currently, it is the most commercialized organic acid worldwide. Acetic acid, in organic process, can be comparable to sulfuric acid in mineral chemical industries, as its movements mirror the ones of the industry as a whole, and a country’s consumption can help to establish the current state of its economy.

While acetic acid solutions have long been produced by ethanol fermentation, nowadays the commercial production of acetic acid is mainly based on methanol carbonylation and liquid-phase oxidation of n-butane.

Acetic Acid Handling. Acetic Acid must be stored away from contact with oxidizing materials, in containers lined with stainless steel, glass, or polyethylene, or made from aluminum. It is usually transported in tank wagons, in amounts intermediate between drum and tank car shipment, with nominal capacities of 38-76 m3, made up of stainless steel or aluminum alloy. The acid is frequently transported and stored in concentrations greater than 99%, since water increases the corrosion power significantly; fortunately, acetic acid is not as hygroscopic as some other anhydrous organic compounds. Higher concentrations (glacial) freeze at around 16 °C, and for this reason, some precautions must be taken depending on the weather. Heating coils, electrical or steam heaters, and vents are usually employed to prevent crystallization.

Acetic Acid Production. Acetic Acid can be produced by biological and synthetic routes. While bacterial fermentation of ethanol is still used for Vinegar manufacture, the most important synthetic routes for the commercial production of Acetic Acid nowadays are based on methanol carbonylation and liquid-phase oxidation of butane, naphtha, or acetaldehyde. Raw materials and the respective production processes employed in the manufacturing of Acetic Acid are listed below.

  • Methanol + carbon monoxide (methanol carbonylation process, rhodium promoted with iodide as catalyst),
  • Acetaldehyde (liquid phase air oxidation process),
  • n-Butane (or naphta) (catalytic liquid phase oxidation process, in the presence of metallic ions (such as cobalt, manganese, or chromium)),
  • Vinyl acetate (ester hydrolysis/isomerization, by product of acetaldehyde production),
  • Ethanol (oxidation process)

Acetic Acid Uses.The uses and applications of Acetic Acid may vary according to its specification. The main forms of Acetic Acid are glacial (99.4 wt% minimum purity); technical grade (usually 80 wt%); dilute (usually 36–37wt%) ; and vinegar (2-12 wt% aqueous solution).

The largest end uses of Acetic Acid are in the production of vinyl acetate monomer and acetic anhydride. Vinyl acetate monomer is primarily a feedstock for the manufacture of poly(vinyl acetate) (PVA) and vinyl acetate copolymers, used in paints, adhesives, paper coatings, and textile treatment. Acetic anhydride, in turn, is a reagent in organic synthesis, mostly used in the production of cellulose acetate textile fibers, cigarette filter tow, and cellulose plastics.
