| − | A colorless volatile liquid solvent that smells and tastes like bananas. Amyl acetate is a mixture of five isomers and is sometimes sold under the names banana oil or pear oil. Its primary isomer is isoamyl acetate. Amyl acetate was introduced in 1887 as a solvent for [[cellulose%20nitrate|cellulose nitrate]] (see [[Zapon%20lacquer|Zapon lacquer]]) and was also later used for [[cellulose%20acetate|cellulose acetate]]. It has also been used in dyeing and finishing textiles, in linoleum oil cloth, and as a banana flavorant. Amyl acetate is still used as a solvent in nail polishes, leather polishes, waterproof varnishes, bronzing liquids, and metallic paints. | + | A type of [[magnetic%20tape|magnetic tape]] used to reproduce sound. Audiotapes are composed of a thin plastic substrate coated with a thin layer of magnetic particles, usually [[ferric%20oxide|ferric oxide]] (Fe2O3) along with small amounts of [[chromium%20dioxide|chromium dioxide]](CrO2). |
