Sec-Butyl acetate is a colorless liquid with a pleasant odor. The vapor mixes well with air, and become explosive mixtures. It reacts with strong oxidants, strong bases, strong acids, and nitrates, causing fi re and explosion hazard.

Watery colorless liquid with a pleasant, fruity odor. Floats on water. Produces irritating vapor.

SEC-BUTYL ACETATE(105-46-4) 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. Dissolves rubber and plastics [USCG, 1999].

Highly flammable. Water soluble.

Flammable, dangerous fire risk. Eye and upper respiratory tract irritant.

During prolonged occupational exposure, sec-butyl acetate causes health effects. The symptoms of toxicity include irritation to the skin and eyes. Exposures to high concentra tions of sec-butyl acetate irritate the nose and throat causing coughing and respiratory distress, headache, nausea, vomiting, dizziness, drowsiness, and coma. After prolonged exposures to sec-butyl acetate, occupational workers show symptoms of severe irritation to the eyes, headache, drowsiness, dryness in the upper respiratory system, skin, and narcosis.

Headaches, dizziness, nausea, irritation of respiratory passage and eyes.

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

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.

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

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

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.

Clear, colorless liquid with a pleasant odor. Odor threshold concentration in air is 2.4 ppb_v (Nagata and Takeuchi, 1990).

sec-Butyl acetate is prepared from sec-butanol and acetic anhydride. It is also prepared from 2-butene under pressure and heated to 115–120C with an excess of glacial acetic acid containing 10% sulfuric acid.
