| Hazard Information | Back Directory | [Chemical Properties]
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. | [General Description]
Watery colorless liquid with a pleasant, fruity odor. Floats on water. Produces irritating vapor. | [Reactivity Profile]
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]. | [Air & Water Reactions]
Highly flammable. Water soluble. | [Hazard]
Flammable, dangerous fire risk. Eye and
upper respiratory tract irritant.
| [Health Hazard]
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 | [Health Hazard]
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. | [Health Hazard]
Headaches, dizziness, nausea, irritation of respiratory passage and eyes. | [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]
Clear, colorless liquid with a pleasant odor. Odor threshold concentration in air is 2.4 ppbv (Nagata
and Takeuchi, 1990). | [Production Methods]
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. | [Synthesis Reference(s)]

Reactivity with Water: No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent. | [Carcinogenicity]
sec-Butyl acetate is not listed as
a carcinogen by ACGIH, California Prop 65, IARC, NTP,
or OSHA. | [Environmental Fate]
Photolytic. The rate constant for the reaction of sec-butyl acetate and OH radicals in the
atmosphere at 300 K is 3.4 x 10-12 cm3/molecule?sec (Hendry and Kenley, 1979).
Chemical/Physical. Slowly hydrolyzes in water forming sec-butyl alcohol and acetic acid. |

During handling of sec-butyl acetate, occupational workers should avoid use of open
flames, sparks, remove all ignition sources, and smoking. The vapor of sec-butyl acetate
mixes well with air, and easily forms explosive mixtures. Workers should avoid using
compressed air for fi lling, discharging, or handling. | [Safety Profile]
An irritant and allergen.
See also ESTERS. Flammable liquid. To
fight fire, use alcohol foam, CO2, dry
chemical. When heated to decomposition it
emits acrid and irritating fumes. | [Hazardous Substances Data]
