[Description]

tert-Butyl acetate, or t-butyl acetate, is a colourless 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 anti-knock properties of motor fuels. tert-Butyl acetate has three isomers: n-butyl acetate, isobutyl acetate, and sec-butyl acetate.
[Appearance]

Butyl acetates are colorless or yellowish liquids with pleasant, fruity odors. There are 4 isomers.

[Chemical Properties]

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.
[General Description]

Colorless liquid with a mild odor. Floats on water. Produces irritating vapor.
[Reactivity Profile]

TERT-BUTYL ACETATE(540-88-5) 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. This compound is incompatible with the following: Nitrates; strong oxidizers, alkalis & acids .
[Air & Water Reactions]

Highly flammable. Insoluble in water.
[Hazard]

Flammable, moderate fire risk. Eye and upper respiratory tract irritant.
[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.
[Health Hazard]

INHALATION: Irritation of throat. EYES: Irritation.
[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
[First aid]

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of salt water and induce vomiting. Do not make an unconscious person vomit.
[Shipping]

UN1123 Butyl acetates, Hazard Class: 3; Labels: 3—Flammable liquid.
[Incompatibilities]

All butyl acetates are incompatible with nitrates, strong oxidizers; strong alkalies; strong acids. Butyl acetates may form explosive mixture with air; reacts with water, on standing, to form acetic acid and n-butyl alcohol. Violent reaction with strong oxidizers and potassium-tert-butoxide. Dissolves rubber, many plastics, resins and some coatings. May accumulate static electrical charges, and may cause ignition of its vapors
[Waste Disposal]

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
[Physical properties]

Colorless 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]

As gasoline additive (Wheeler et al.).
[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.
[Application]

tert-Butyl acetate can be used to convert:
Aromatic nitriles to the corresponding N-tert-butylamides catalyzed by sulfuric acid.
S-tert-Butyl-L-cysteine hydrochloride to S-tert-butyl-L-cysteine tert-butyl ester hydrochloride.
Lanthanide isopropoxides to lanthanide tert-butoxides in cyclohexane.
[Production Methods]

tert-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 .

[Flammability and Explosibility]

Highlyflammable
[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).
[Purification Methods]

Wash the ester with 5% Na2CO3 solution, then saturated aqueous CaCl2, dry with CaSO4 and distil it. [McClosky et al. Org Synth Coll Vol IV 263 1963, Mangia et al. Org Prep Proc Int 18 13 1986, Beilstein 2 IV 151.]

[storage]

tert-Butyl acetate should be stored in a cool, dry, well-ventilated area in tightly sealed containers that are labeled in accordance with regulatory standards. Containers of tert butyl acetate should be protected from physical damage and should be stored separately from nitrates, strong oxidizers, strong acids, strong alkalis, heat, sparks, and open flame. Because containers that formerly contained tert-butyl acetate may still hold product resi dues, they should be handled appropriately
[Precautions]

If exposures to tert-butyl acetate or a solution in work areas gets into the eyes, immediately fl ush the eyes with large amounts of water for a minimum of 15 min, lifting the lower and upper lids occasionally. Always use safety goggles or eye protection in combination with breathing protection.
[Safety Profile]

Poison 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.
