Beschreibung
Ethyl benzoate, C₉H₁₀O₂, is the ester formed by the condensation of benzoic acid and ethanol. It is a colorless liquid that is almost insoluble in water, but miscible with most organic solvents.
As with many volatile esters, ethyl benzoate has a pleasant odor which could be described similar to wintergreen mint. It is a component of some artificial fruit flavors.
Chemische Eigenschaften
Ethyl benzoate is a colourless liquid that has a somewhat fruity odor similar to ylang-ylang, but milder than methyl benzoate. Soluble in ethanol, ethyl ether, petroleum ether, propylene glycol, mineral oil and most non-volatile oils, insoluble in water and glycerin.
Occurrence
Reported found in volatiles from hard, mature peaches, pineapple and currant. Also reported found in apple juice, banana, guava, cranberry, raspberry, sweet cherry, Parmesan cheese, butter, milk, white wine, red wine, cider, whiskies, cocoa, black tea, fresh plum, apple brandy, cherry brandy, Bourbon vanilla, naranjilla fruit, ceriman or pinanona, pimento berry, olive and passion fruit.
Verwenden
Ethyl benzoate is used as a perfume scent. It acts as a food flavoring agent. It is an active component of artificial fruit flavors. Further, it is used in cosmetics and personal care products as fragrance ingredients and preservatives.
Verwenden
Ethyl Benzoate acts as an aroma and flavour compound due to the volatile ester group in its structure. In perfumery under the name Essence de Niobe; in manufacture of Peau d'Espagne; artificial fruit essence.
Definition
ChEBI: Ethyl benzoate is a benzoate ester obtained by condensation of benzoic acid and ethanol. It is a volatile oil component found in ripe kiwifruit, cranberry juice, and palm kernel oil. It has a role as a flavouring agent, a fragrance and a volatile oil component. It is a benzoate ester and an ethyl ester.
synthetische
By esterification of ethyl alcohol and benzoic acid in the presence of anhydrous aluminum sulfate and a trace of sulfuric acid; by transesterification of methyl benzoate with ethanol in the presence of potassium ethylate
Aroma threshold values
Detection: 100 ppb; recognition: 150 ppb
Taste threshold values
Taste characteristics at 30 ppm: sweet, medicinal, green, minty, fruity, birch beer and wintergreen-like.

Sicherheitsprofil
Moderately toxic by ingestion. Mildly toxic by skin contact. A skin and eye irritant. Combustible liquid when exposed to heat or flame; can react with oxidizing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS
