개요

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.

화학적 성질

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

출처

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.

용도

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.

제조 방법

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

생산 방법

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.

일반 설명

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.

공기와 물의 반응

Highly flammable. Insoluble in water.

반응 프로필

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].

위험도

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

건강위험

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

화재위험

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

화학 반응

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.

Safety Profile

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.

잠재적 노출

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.

운송 방법

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

Purification Methods

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

비 호환성

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

폐기물 처리

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
