Chemical PropertiesClear, colorless liquid
tert-Butyl acetate or t-butyl acetate is a colorless flammable liquid with a camphoror blueberry-like smell. It is used as a solvent in the production of lacquers, enamels, inks, adhesives, thinners, and industrial cleaners. It is also used as an additive to improve the antiknock properties of motor fuels. tert-Butyl acetate has three isomers: n-butyl acetate, isobutyl acetate, and sec-butyl acetate.
Chemical PropertiesButyl acetates are colorless or yellowish liquids with pleasant, fruity odors. There are 4 isomers.
Physical propertiesColorless liquid with a fruity odor. Odor threshold concentration in water is 4 ppm (CHRIS, 1994). Nagata and Takeuchi (1990) reported an odor threshold concentration of 71 ppbv.
Uses：Gasoline additive; lacquer solvent
Uses： Tert-butyl Acetate is a common solvent used in the production of various industrial cleansers, thinners and adhesives and is also known as a VOC.
Uses： As gasoline additive (Wheeler et al.).
Production MethodsTert-Butyl acetate is prepared from isobutylene reacting with acetic acid in the liquid phase with vanadium pentoxideimpregnated silica as the catalyst and with heat to increase the yield .

General DescriptionColorless liquid with a mild odor. Floats on water. Produces irritating vapor.
Air & Water ReactionsHighly flammable. Insoluble in water.
Reactivity ProfileTert-Butyl acetate is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. tert-Butyl acetate is incompatible with the following: Nitrates; strong oxidizers, alkalis & acids .
HazardFlammable, moderate fire risk. Eye and upper respiratory tract irritant.
Health Hazard INHALATION: Irritation of throat. EYES: Irritation.
Health Hazard Exposure to tert-butyl acetate causes eye, skin, and respiratory irritation in workers. By analogy with the effects of exposure to similar esters, tert-butyl acetate may act as a CNS depressant at high concentrations. The signs and symptoms of acute exposure to tert-butyl acetate include, but are not limited to, itchy or inflamed eyes and irritation of the nose and upper respiratory tract. Exposures to tert-butyl acetate at high concentrations may cause headache, drowsiness, and other narcotic effects.
Safety ProfilePoison by inhalation and ingestion. Flammable. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.
Potential Exposure n-Butyl acetate is an important solvent in the production of lacquers, leather and airplane dopes, and perfumes. It is used as a solvent and gasoline additive. sec-Butyl acetate is used as a widely used solvent for nitrocellulose, nail enamels and many different purposes. tert-Butyl acetate is common industrial solvent used in the making of lacquers, artificial leather, airplane dope, perfume; and as a food additive. Isobutyl acetate is used as a solvent and in perfumes and artificial flavoring materials
Environmental fate Chemical/Physical. Hydrolyzes in water to tert-butyl alcohol and acetic acid. The estimated hydrolysis half-life at 25 °C and pH 7 is 140 yr (Mabey and Mill, 1978).
