Acetic acid, also known as  Ethylic acid with CH3COOH formula, is safe to handle, cost efficient, and easy to recover, by its extensive use in different fields. It is an important bulk chemical that is nowadays produced through methanol carbonylation (CH3OH+CO→CH3COOH).

Chemical structure Acetic acid

Also, glacial acetic acid, that is a pure acetic acid and entirely soluble in water, is a colorless, corrosive liquid with boiling point 117.9 °C (244.2 °F) and melting point 16.6 °C (61.9 °F).


Acetic acid crystals are orthorhombic, space group Pna21, with a= 13.324±0.02, b = 4.08±0-01, c= 5.774±0.01 Å from single-crystal X-ray diffraction. The structure is similar to that of formic acid with molecules linked into infinite chains by hydrogen bonds. The bond distances are C-C = 1.54 Å, C=O = 1.24 Å, C-O = 1.29 Å, and O-H • • • O = 2.61 Å, each ±0.02 Å, by least-squares refinement. The four heavy atoms of each molecule stand in a plane. The coherence between chains is due to van der Waals forces.


Acetic acid is one of the most widely used materials in today’s industrial society, which we will discuss the most important applications of this material in below.

Acetic acid is used in lots of industrial processes for the production of substrates and it’s often a chemical reagent for the production of chemical compounds. Acetic acid has largest use in the production of materials such as vinyl acetate monomer. also Glacial acetic acid used in recrystallization as solvent because it can purify organic compounds.

The imperative use of acetic acid is the production of vinyl acetate monomer (VAM). In 2008, this application was estimated to consume a third of the world’s production of acetic acid.

Solvents of inks and paints are made by acetic acid and related alcohol that is a kind of the main esters of acetic acid.

Almost nearly 30% of the global production is used in production of acetic anhydride; so it can be called that one of the significant applications.

Safety information

Hazards of solutions of acetic acid belong to the concentration. The following table lists the EU Classification of acetic acid solutions:

by weight
Molarity Classification
10–25% 1.67–4.16 mol/L Irritant (Xi)
25–90% 4.16–14.99 mol/L Corrosive (C)
>90% >14.99 mol/L Corrosive (C) Flammable (F)


  • Flammable liquid and vapor [Warning Flammable liquids]
  • Causes intense skin burns and eye injury [Danger Skin corrosion/irritation]
  • When spilled in water all forms will mix rapidly and produce an irritating vapor.
