2-Ethylbutyric acid Chemical Properties,Usage,Production
Chemical Properties
clear colorless to light yellow liquid
Chemical Properties
2-Ethylbutyric acid has a rancid, oily-fruity, acidulous odor
Occurrence
Reported found in guava fruit, wheaten bread and cheeses (Parmesan, blue, cheddar, provolone, Romano and goat), apple, banana, grape, melon, papaya, peach, pineapple and more.
Uses
2-Ethylbutyric acid is used as the internal standard for determining volatile fatty acids (VFAs) in wastewater from the constructed wetlands. It is used in the determination of both free and fatty acids in milk and milk products by HPLC method with direct derivatisation.
Uses
2-Ethylbutyric Acid is a flavoring agent that is a clear liquid, color- less, with a rancid odor. it is miscible in alcohol and ether, sparingly soluble in water, and is obtained by chemical synthesis.
Uses
Ester formation; intermediate for drugs, dyestuffs, chemicals; flavoring.
Preparation
By catalytic oxidation of diethylacetaldehyde or by decarboxylation of diethylmalonic acid.
Definition
ChEBI: 2-Ethylbutanoic acid is a branched-chain fatty acid.
Aroma threshold values
Detection: 15 to 600 ppb
Taste threshold values
Taste characteristics at 35 ppm: acidic, fruity, tropical with a creamy aftertaste.
Safety Profile
Moderately toxic by ingestion and skin contact. An irritant to skin and mucous membranes. A severe eye irritant. See also ESTERS. Narcotic in high concentrations. Flammable liquid. To fight fire, use CO2, dry chemical, alcohol foam. When heated to decomposition it emits acrid smoke and fumes.
