Acetic Acid has a place in the organic chemical industry comparable to sulphuric acid in the inorganic chemical industry. Acetic Acid is used for the production of vinyl acetate, an important monomer. Acetic Acid is used in the fermentation industry in large-scale amino acids (qv) production and as the substrate of choice for the production of many dietary supplements, eg, glutamic acdid, citric acid, and lysine. Cellulose acetate (qv) was formerly the foremost of synthetic polymers and is still an important thermoplastic and fiber constituent, used in the manufacture of plastic sheeting film and in the formulation of lacquers. Acetic Acid is used as the solvent in liquid-phase oxidation of p-xylene to terephthalic acid. The principal use for acetate esters, from methyl through amyl, is as solvents may be made obsolete by air pollution legislation, although these laws have not been promulgated as rapidly as first expected. Acetic Acid is an effective fungicide used to control the fungi that cause ropiness in bread; to preserve high moisture grain and in combination with propionic acid, to combat Aspergillus flavus, the organism responsible for producing allatoxin in grain.
Any solution containing more than half acetic acid in water or organic solvents is considered corrosive. These solutions cause damage to skin, eyes, nose, and mouth. There is no burning sensation upon application to unbroken skin, although symptoms appear as blisters within 30 minutes to 4 hour. There is little or no pain experienced, unless sensory nerve receptors are attacked. Medical care should be sought immediately. Particular care is needed when handling acetic acid to avoid spilling it on the skin or clothing and to avoid breathing the vapors. When exposed, with acetic acid away with large amounts of water or dilute sodium bicarbonate solution. Washing blisters that have already appeared will not alleviate the pain. Leave areas where the odor of acetic acid vapors is noticeable. Glacial acetic acid causes severe gastric difficulties if swallowed, but the precise toxic dose for humans is not known. OSHA standard for air in work places is a time-weighted average of 10 ppm.
