説明

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.

化学的特性

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.

化学的特性

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

化学的特性

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

化学的特性

colourless liquid with a fruity odour

天然物の起源

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.

使用

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.

使用

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

調製方法

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.

製造方法

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

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.

一般的な説明

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.

空気と水の反応

Highly flammable. Insoluble in water.

反応プロフィール

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].

危険性

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

健康ハザード

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

火災危険

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

化学反応性

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.

安全性プロファイル

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.

職業ばく露

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

Carcinogenicity

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

輸送方法

UN1180; UN1178 Ethyl butyrate, Hazard Class: 3; Labels: 3-Flammable liquid

純化方法

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

不和合性

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

廃棄物の処理

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
