• Beschreibung

  Ethyl butyrate, also known as ethyl butanoate, or butyric ether, is an ester with the chemical formula CH₃CH₂CH₂COO.CH₂CH₃.It is soluble in propylene glycol, paraffin oil, and kerosene.It has a fruity odor, similar to pineapple.

• Chemische Eigenschaften

  colourless liquid with a fruity odour

• Chemische Eigenschaften

  Ethyl butyrate has a fruity odor with pineapple undertone and sweet, analogous taste.

• Chemische Eigenschaften

  Ethyl Butyrate occurs in fruits and alcoholic beverages, but also in other foods such as cheese. It has a fruity odor, reminiscent of pineapples. Large amounts are used in perfume and in flavor compositions.

• Chemische Eigenschaften

  Ethyl butyrate is a colorless liquid. Pineapple odor. The Odor Threshold is 0.015 ppm.

• Occurrence

  Identified by gas chromatography in olive oil and other vegetable oils. Reported found in apple, banana, citrus peel oils and juices, cranberry, blueberry, black currants, guava, grapes, papaya, strawberry, onion, leek, cheeses, chicken, beef, beer, cognac, rum, whiskies, cider, sherry, grape wines, coffee, honey, soybeans, olives, passion fruit, plums, mushroom, mango, fruit brandies, kiwifruit, mussels and pawpaw.

• Verwenden

  Ethyl butyrate is used in flavors and fragrances. It is used as a solvent in perfumery products, and as a plasticizer for cellulose. It is used in the preparation of novel 2-cyanopyrimidines as cathespin K inhibitors. It is also used in the synthesis of pyridobenzimidazole derivatives exhibiting antifungal activity by the inhibition of β-1,6-glucan.

• Verwenden

  It is commonly used as artificial flavoring resembling orange juice or pineapple in alcoholic beverages (e.g. martinis, daiquiris etc.), as a solvent in perfumery products, and as a plasticizer for cellulose. In addition, ethyl butyrate is often also added to orange juice, as most associate its odor with that of fresh orange juice.
  Ethyl butyrate is one of the most common chemicals used in flavors and fragrances. It can be used in a variety of flavors: orange (most common), cherry, pineapple, mango, guava, bubblegum, peach, apricot, fig, and plum. In industrial use, it is also one of the cheapest chemicals, which only adds to its popularity.

• Verwenden

  manufacture of artificial rum; perfumery; the alcoholic solution constitutes the so-called "pineapple oil".

• Definition

  ChEBI: Ethyl butyrate is a butyrate ester resulting from the formal condensation of the hydroxy group of ethanol with the carboxy group of butyric acid. It has a role as a plant metabolite. It is functionally related to an ethanol.

• synthetische

  By esterification of n-butyric acid with ethyl alcohol in the presence of Twichell’s reagent or MgCI2; also by heating n-butyl alcohol and ethanol over CuO + UO3 catalyst at 270°C

• Vorbereitung Methode

  Ethyl Butyrate can be synthesized by reacting ethanol and butyric acid. This is a condensation reaction, meaning water is produced in the reaction as a byproduct.

• Aroma threshold values

  Detection: 0.1 to 18 ppb

• Taste threshold values

  Taste characteristics at 20 ppm: fruity, sweet, tutti-frutti, apple, fresh and lifting, ethereal.

• Allgemeine Beschreibung

  A clear colorless liquid with a pineapple-like odor. Flash point 78°F. Less dense than water and insoluble in water. Vapors heavier than air.

• Air & Water Reaktionen

  Highly flammable. Insoluble in water.

• Reaktivität anzeigen

  Ethyl butyrate 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. May attack some forms of plastics [USCG, 1999].

• Hazard

  Irritant to eyes and mucous membranes, narcotic in high concentration. Flammable, dangerous fire risk.

• Health Hazard

  Inhalation or ingestion causes headache, dizziness, nausea, vomiting, and narcosis. Contact with liquid irritates eyes.

• Brandgefahr

  Behavior in Fire: Vapor is heavier than air and may travel to a source of ignition and flash back. Containers may explode in fire.

• Flammability and Explosibility

  Flammable

• Chemische Reaktivität

  Reactivity with Water: No reaction; Reactivity with Common Materials: May attack some forms of plastics; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

• Sicherheitsprofil

  Wdly toxic by ingestion. A skin irritant. Flammable liquid when exposed to heat or flame; can react vigorously with oxidizing materials. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS.

• mögliche Exposition

  Ethyl butyrate, and aldehyde, is used in flavorings, extracts, perfumery, and as a solvent.

• Erste Hilfe

  If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seekmedical attention immediately. If this chemical contactsthe skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove fromexposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing hasstopped and CPR if heart action has stopped. Transferpromptly to a medical facility. When this chemical hasbeen swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

• Carcinogenicity

  Not listed by ACGIH, California Proposition 65, IARC, NTP, or OSHA.

• Lager

  Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Prior to working with this chemical you should be trainedon its proper handling and storage. Ethyl butyrate is incompatible with oxidizers (such as perchlorates, peroxides, permanganates, chlorates, and nitrates), strong acids (such ashydrochloric, sulfuric, and nitric), bases, and heat. Store intightly closed containers in a cool, well-ventilated area.Sources of ignition, such as smoking and open flames, areprohibited where ethyl butyrate is handled, used, or stored.Metal containers involving the transfer of 5 gallons or moreof ethyl butyrate should be grounded and bonded. Drumsmust be equipped with self-closing valves, pressure vacuumbungs, and flame arresters. Use only nonsparking tools andequipment, especially when opening and closing containersof ethyl butyrate.

• läuterung methode

  Dry the ester with anhydrous CuSO4 and distil it under dry nitrogen. [Beilstein 2 IV 787.]

• Inkompatibilitäten

  Vapor explosive mixture with air. Ethers can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert. Incompatible with alkaline materials, strong acids, oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from strong bases and heat

• 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
