使用
Ethyl Isobutyrate is a synthetic flavoring agent that is a stable, colorless liquid of dry, fruity odor. it should be stored in tin, glass, or resin-lined containers. it is used to give fruity effects to flavors for applications in candy, baked goods, and beverages at 10–100 ppm.
製造方法
By esterification of ethanol with isobutyric acid under azeotropic conditions.
定義
ChEBI: Ethyl isobutyrate is a fatty acid methyl ester obtained by the formal condensation of isobutyric acid with ethanol. It has a role as a metabolite. It is functionally related to an isobutyric acid.
一般的な説明
Ethyl isobutyrate appears as a colorless volatile liquid with a fruity, aromatic odor. Less dense than water and insoluble in water. Vapors heavier than air. May irritate skin and eyes. Used to make flavoring extracts and other chemicals.
空気と水の反応
Highly flammable. Insoluble in water.
反応プロフィール
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.
健康ハザード
May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
火災危険
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.
安全性プロファイル
Moderately toxic by
intraperitoneal route. A skin irritant.
Flammable liquid. A very dangerous fire
hazard when exposed to heat or flame; can
react vigorously with oxidizing materials. To
fight fire, use foam, CO2, dry chemical.
When heated to decomposition it emits
acrid smoke and irritating fumes. See also
ESTERS.
純化方法
Wash the ester with aqueous 5% Na2CO3, then with saturated aqueous CaCl2. Dry it over CaSO4 and distil. [Beilstein 1 IV 846.]
