Product Description

Acetic acid is the most commonly used and preferred IUPAC name. The systematic name ethanoic acid, a validIUPAC name, is constructed according to the substitutive nomenclature. The name acetic acid derives from acetum, the Latin word for vinegar, and is related to the word acid itself.

Glacial acetic acid is a name for water-free (anhydrous) acetic acid. Similar to the German name Eisessig (ice-vinegar), the name comes from the ice-like crystals that form slightly below room temperature at 16.6 °C (61.9 °F) (the presence of 0.1% water lowers its melting point by 0.2 °C).

 Usage:-
Acetic acid is a chemical reagent for the production of chemical compounds. The largest single use of acetic acid is in the production of vinyl acetate monomer, closely followed by ester production. The volume of acetic acid used in vinegar is comparatively small.

The major use of acetic acid is for the production of vinyl acetate monomer (VAM).

Glacial acetic acid is an excellent polar protic solvent, as noted above. It is frequently used as a solvent for recrystallization to purify organic compounds. Acetic acid is used as asolvent in the production of terephthalic acid (TPA), the raw material for polyethylene terephthalate (PET).


Health effects and safety:-

Concentrated acetic acid is corrosive to skin and must, therefore, be handled with appropriate care, since it can cause skin burns, permanent eye damage, and irritation to the mucous membranes.These burns or blisters may not appear until hours after exposure. Latex gloves offer no protection, so specially resistant gloves, such as those made of nitrile rubber, are worn when handling the compound.

Concentrated acetic acid can be ignited with difficulty in the laboratory. It becomes a flammable risk if the ambient temperature exceeds 39 °C (102 °F), and can form explosive mixtures with air above this temperature (explosive limits: 5.4-16%).

Acetic acid is a strong eye, skin, and mucous membrane irritant. Prolonged skin contact with glacial acetic acid may result in tissue destruction. Inhalation exposure (eight hours) to acetic acid vapours at 10 ppm could produce some irritation of eyes, nose, and throat; at 100 ppm marked lung irritation and possible damage to lungs, eyes, and skin might result. Vapour concentrations of 1,000 ppm cause marked irritation of eyes, nose and upper respiratory tract and cannot be tolerated.


The hazards of solutions of acetic acid depend on the concentration. The following table lists the EU classification of acetic acid solutions:

Concentration by weight	Molarity	Classification	R-Phrases
10-25%	1.67-4.16 mol/L	Irritant (Xi)	R36/38
25-90%	4.16-14.99 mol/L	Corrosive (C)	R34
>90%	>14.99 mol/L	Corrosive (C) Flammable (F)	R10, R35

Solutions at more than 25% acetic acid are handled in a fume hood because of the pungent, corrosive vapor. Dilute acetic acid, in the form of vinegar, is practically harmless. However, ingestion of stronger solutions is dangerous to human and animal life. It can cause severe damage to the digestive system, and a potentially lethal change in the acidity of the blood.
