Chemische Eigenschaften
Ethyl Isovalerate is a colorless liquid
with a fruity odor reminiscent of blueberries. It occurs in fruits, vegetables, and
alcoholic beverages. It is used in fruit aroma compositions.
Occurrence
Reported found in pineapple, orange juice and peel oil, bilberry, blueberry, strawberry, Swiss cheese, other
cheeses, beer, cognac, rum, cider, whiskey, sherry, grape wines, cocoa, passion fruit, mango and mussels.
Verwenden
In alcohol solution for flavoring confectionery and beverages.
Definition
ChEBI: The fatty acid ethyl ester of isovaleric acid.
synthetische
By esterification of isovaleric acid with ethyl alcohol in the presence of concentrated H2SO4.
Vorbereitung Methode
Ethyl isovalerate is produced by combining isovaleric acid
and ethanol in the presence of concentrated sulfuric acid or
hydrochloric acid ester followed by distillation .
Allgemeine Beschreibung
A colorless oily liquid with a strong odor similar to apples. Less dense than water. Vapors heavier than air. Flash point 77°F. May mildly irritate skin and eyes.
Air & Water Reaktionen
Highly flammable. Slightly soluble in water.
Reaktivität anzeigen
ETHYL ISOVALERATE 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.
Health Hazard
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Carcinogenicity
Not listed by ACGIH, California
Proposition 65, IARC, NTP, or OSHA.
läuterung methode
Wash the ester with aqueous 5% Na2CO3, then saturated aqueous CaCl2. Dry it over CaSO4 and distil. [Beilstein 2 IV 898.]
