General description

Acetic acid is an aliphatic organic acid. It is a hygroscopic, corrosive liquid with a vinegar-like odor. It can be synthesized by oxidizing acetaldehyde in the presence of manganese or cobalt salts. It is utilized for synthesizing acetic anhydride, cellulose acetate and acetic esters. Its impact on the degradation of historic paper has been analyzed.
