Product Description
Acetic acid is the second simplest carboxylic acid (after formic acid) and is an important chemical reagent and industrial chemical, mainly used in the production of cellulose acetate for photographic film and polyvinyl acetate for wood glue, as well as synthetic fibers and fabrics. In households, diluted acetic acid is often used in descaling agents. In the food industry, acetic acid is used under thefood additive code E260 as an acidity regulator and as a condiment.
According to GB/1903_2008,by fermentation method, corn is fermentated into alchohol vapors.After oxidization reaction, we got acetaldehyde ,then it is further putified by re-distillation ,then got qualified acetic acid.

Application:-
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.
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. These predictions were based on animal experiments and industrial exposure.
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.
Due to incompatibilities, it is recommended to keep acetic acid away from chromic acid, ethylene glycol, nitric acid, perchloric acid, permanganates, peroxides and hydroxyls.
