Description
A colorless, liquid with a pleasant fruity smell. Ethyl acetate is Hygroscopic and slowly decomposes in the presence of water to form acids. Ethyl acetate is primarily used as a Solvent for Cellulose nitrate, paints, varnishes, lacquers, and airplane dopes. It is also used in the manufacture of photographic films, rayon, synthetic leather, perfumes, and flavorings.
Synonyms and Related Terms
