Description
A colorless, volatile liquid with a characteristic fruity odor. Acetaldehyde reacts as a reducing agent when mixed with Tollen's reagent (ammonia - Silver nitrate) to form metallic silver on mirrors. It is used in the manufacture of paraldehyde, perfumes, flavors, aniline dyes, plastics, synthetic rubber, explosives. Acetaldehyde is also used to harden gelatin fibers and as a preservative and flavoring agent in foods and beverages.
