Verwenden
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.
synthetische
By esterification of ethanol with isobutyric acid under azeotropic conditions.
Definition
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.
Allgemeine Beschreibung
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.
Air & Water Reaktionen
Highly flammable. Insoluble in water.
Reaktivität anzeigen
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.
Health Hazard
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.
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.
Sicherheitsprofil
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.
läuterung methode
Wash the ester with aqueous 5% Na2CO3, then with saturated aqueous CaCl2. Dry it over CaSO4 and distil. [Beilstein 1 IV 846.]
