  • Chemische Eigenschaften Butyl acetate has a strong, fruity odor; burning and then sweet taste reminiscent of pineapple.
  • Occurrence Reported present in rum ether, pears, pear brandy, cider, mango, mountain papaya (C. pubescens), soybean, roasted peanuts and honey and other natural products.
  • Verwenden n-Butyl acetate is used in the manufactureof lacquers, plastics, photographic films, andartificial leathers.
  • Verwenden Butyl Acetate is a flavoring agent which is a clear, colorless liquid possessing a fruity and strong odor. it is sparingly soluble in water and miscible in alcohol, ether, and propylene glycol. it is also termed n-butyl acetate.
  • Verwenden manufacture of lacquer, artificial leather, photographic films, plastics, safety glass.
  • Definition ChEBI: The acetate ester of butanol.
  • synthetische By esterification of n-butyl alcohol with acetic acid.
  • Aroma threshold values Detection: 10 to 500 ppb
  • Allgemeine Beschreibung A clear colorless liquid with a fruity odor. Flash point 72 - 88°F. Density 7.4 lb / gal (less than water). Hence floats on water. Vapors heavier than air.
  • Air & Water Reaktionen Highly flammable. Very slightly soluble in water.
  • Reaktivität anzeigen 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. Attacks many plastics. [Handling Chemicals Safely 1980. p. 233].
  • Hazard Skin irritant, toxic. Flammable, moderate fire risk. Eye and upper respiratory tract irritant.
  • Health Hazard The narcotic effects of n-butyl acetate isgreater than the lower alkyl esters of aceticacid. Also, the toxicities and irritant actionsare somewhat greater than n-propyl, iso propyl, and ethyl acetates. Exposure to itsvapors at about 2000 ppm caused mild irri tation of the eyes and salivation in test ani mals. A 4-hour exposure to 14,000 ppm wasfatal to guinea pigs. In humans, inhalation of300–400 ppm of n-butyl acetate may pro duce moderate irritation of the eyes andthroat, and headache.
  • Health Hazard Exposures to n-butyl acetate cause harmful effects that include, but are not limited to, coughing and shortness of breath. High concentrations have a narcotic effect, with symp toms such as sore throat, abdominal pain, nausea, vomiting, and diarrhea. High concen trations of n-butyl acetate cause severe poisoning. Prolonged periods of exposure cause adverse effects to the lungs, the nervous system, and the mucous membranes. Repeated skin contact causes skin dryness or cracking, and dermatitis
  • Health Hazard SKIN: prolonged or frequently repeated exposures may lead to drying. INHALATION: headaches, dizziness, nausea, irritation of respiratory passages and eyes.
  • Brandgefahr HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
  • Brandgefahr Flash Point (°F): 99 ℃, 75 ℃; Flammable Limits in Air (%): 1.7-7.6; Fire Extinguishing Agents: Foam, dry chemical, carbon dioxide; Fire Extinguishing Agents Not To Be Used: Water in straight hose stream will scatter and spread fire and should be avoided; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Not pertinent; Ignition Temperature (°F): 760; Electrical Hazard: Class I, Group D; Burning Rate: 4.4 inm/min.
  • Chemische Reaktivität 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.
  • Sicherheitsprofil Moderately toxic by intraperitoneal route. Mdly toxic by inhalation and ingestion. An experimental teratogen. A skin and severe eye irritant. Human systemic effects by inhalation: conjunctiva irritation, unspecified nasal and respiratory system effects. A mild allergen. High concentrations are irritating to eyes and respiratory tract and cause narcosis. Evidence of chronic systemic toxicity is inconclusive. Flammable liquid. Moderately explosive when exposed to flame. Ignites on contact with potassium tert-butoxide. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits acrid and irritating fumes. See also ESTERS.
  • mögliche Exposition 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
  • Erste Hilfe 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.
  • Lager n-Butyl acetate should be kept stored in a segregated and approved area. Workers should keep the container in a cool, well-ventilated area, closed tightly, and sealed until ready for use. Workers should avoid all possible sources of ignition/spark at the workplace
  • Versand/Shipping UN1123 Butyl acetates, Hazard Class: 3; Labels: 3—Flammable liquid.
  • läuterung methode Distil, reflux with successive small portions of KMnO4 until the colour persists, dry with anhydrous CaSO4, filter and redistil. [Beilstein 2 IV 143.]
  • Inkompatibilitäten 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.
  • Vorsichtsmaßnahmen On exposure to n-butyl acetate, immediately wash with plenty of water, also under the eyelids, for at least 15 min. Remove contact lenses. n-Butyl acetate is flammable in the pres ence of open flames, sparks, oxidizing materials, acids, and alkalis. It poses explosion risk in the presence of mechanical impact. For health safety, management authorities should provide exhaust ventilation facilities at the workplace to keep the airborne concentrations of vapors of n-butyl acetate below TLV
