Ethyl propionate Chemical Properties,Uses,Production
Description
Ethyl propionate is a carboxylic acid ester compound containing ester group functionalities. Due to its distinctive fruity flavour, Ethyl propionate is widely used as a food flavouring and as a fragrance in cosmetics. However, it is flammable and hazardous to humans and may damage the liver and kidneys, and high exposures can cause drowsiness and sleepiness. High exposures may affect the heart and it has been added to the list of special health hazards.
Chemical Properties
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.
Uses
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.
Production Methods
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.
General Description
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 Reactions
Highly flammable. Insoluble in water.
Reactivity Profile
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.
Safety Profile
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.
Purification Methods
Treat the ester with anhydrous CuSO4 and distil it under nitrogen. [Beilstein 2 IV 205.]
Toxicity evaluation
Ethyl propionate oral toxicity Sprague-Dawley rat LD50 (male) = 10.8 (8.9-13.1) mL/kg; LD50 (female) = 9.8 (7.2-13.6) mL/kg; LD50 = 8.0 mL/kg. Dermal toxicity: New Zealand White rabbit LD50 > mL/kg[1].
