Chemische Eigenschaften
Ethyl Propionate is a clear colorless to pale yellow liquid that is found in many fruits and alcoholic beverages. It has a fruity odor reminiscent of rum and is used in flavor compositions for creating both fruity and rum notes.
Occurrence
Reported found in several types of wine, in white grape var. Sauvignon, cocoa, apple juice, orange juice, grapefruit juice, guava, melon, peach, pineapple, strawberry, tomato, various cheeses, beer, cognac, rum, whiskey, bourbon, malt whiskey,
scotch, cider, brandy, kiwi fruit and mussels.
Verwenden
Ethyl Propionate is a flavoring agent that is a transparent liquid,
colorless, with an odor resembling rum. it is miscible in alcohol and
propylene glycol, soluble in fixed oils, mineral oil, and alcohol, and
sparingly soluble in water. it is obtained by chemical synthesis.
Vorbereitung Methode
Ethyl propionate is produced by the esterification of ethyl
alcohol with propionic acid or propionic anhydride.
Definition
ChEBI: Ethyl propionate is a propanoate ester of ethanol. It has a role as a metabolite.
Allgemeine Beschreibung
Ethyl propionate[105-37-3] appears as a clear colorless liquid with a pineapple-like odor. Flash point 54 °F. Less dense than water and insoluble in water. Vapors are heavier than air.
Air & Water Reaktionen
Highly flammable. Insoluble in water.
Reaktivit?t anzeigen
Ethyl propionate 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. Can react with oxidizing agents, bases, and acids. Polymerization: Will not polymerize [USCG, 1999].
Hazard
Flammable, dangerous fire risk.
Health Hazard
Exposure can cause irritation of eyes, nose and throat. May cause shortness of breath or coughing. High concentrations have a narcotic effect. May cause abdominal pain and vomiting if swallowed.
Sicherheitsprofil
Moderately toxic by
ingestion and intraperitoneal routes. A skin
and eye irritant. A flammable liquid. A very
dangerous fire and explosion 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
ETHERS.
l?uterung methode
Treat the ester with anhydrous CuSO4 and distil it under nitrogen. [Beilstein 2 IV 205.]
