Description |
Ethyl isovalerate is the ethyl ester form of isovalerate formed between ethyl alcohol with isovaleric acid. It is a derivative of valeric acid, mainly found in fruits (one of the major component of blueberry). It is a kind of natural food flavoring agent with a fruity type odor and flavor. It is widely used in perfumery and fragrance. It is now frequently synthesized using surfactant-coated lipase (various kinds of origins) immobilized in magnetic nanoparticles. |
|
Chemical Properties |
clear colorless to pale yellowish liquid |
|
Chemical Properties |
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. |
|
Chemical Properties |
Ethyl isovalerate has a strong, fruity, vinous, apple-like odor on dilution. |
|
Uses |
In alcohol solution for flavoring confectionery and beverages. |
|
Production Methods |
Ethyl isovalerate is produced by combining isovaleric acid and ethanol in the presence of concentrated sulfuric acid or hydrochloric acid ester followed by distillation . |
|
Production Methods |
Ethyl isovalerate is produced by combining isovaleric acid and ethanol in the presence of concentrated sulfuric acid or hydrochloric acid ester followed by distillation. |
|
Preparation |
By esterification of isovaleric acid with ethyl alcohol in the presence of concentrated H2SO4. |
|
Aroma threshold values |
Detection: 0.01 to 0.4 ppb |
|
Taste threshold values |
Taste characteristics at 30 ppm: fruity, sweet, estry and berry-like with a ripe, pulpy fruity nuance. |
|
General Description |
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 Reactions |
Highly flammable. Slightly soluble in water. |
|
Reactivity Profile |
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. |
|
Purification Methods |
Wash the ester with aqueous 5% Na2CO3, then saturated aqueous CaCl2. Dry it over CaSO4 and distil. [Beilstein 2 IV 898.] |
