Ethyl benzoate, C 9 H 10 O 2, is an 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 described as sweet, wintergreen, fruity, medicinal, cherry and grape. [1]
Benzoic acid occurs naturally as do its esters in many plant and animal species. Appreciable amounts are found in most berries (around 0.05%). Ripe fruits of several Vaccinium species (e.g., cranberry, V. vitis macrocarpon; bilberry, V. myrtillus) contain as much as 0.03–0.13% free benzoic acid.
An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).
PRL-8-53 is a nootropic substituted phenethylamine that has been shown to act as a hypermnesic drug in humans; it was first synthesized by medical chemistry professor Nikolaus Hansl at Creighton University in the 1970s as part of his work on amino ethyl meta benzoic acid esters. [1] [2]
Ethylparaben (ethyl para-hydroxybenzoate) is the ethyl ester of p-hydroxybenzoic acid. Its formula is HO-C 6 H 4-CO-O-CH 2 CH 3. It is a member of the class of compounds known as parabens. It is used as an antifungal preservative. As a food additive, it has E number E214.
PALM BEACH GARDENS, Fla. (AP) — Tiger Woods had 199 yards to the hole. His Jupiter Links teammates realized too late that something was dreadfully wrong Tuesday night in a TGL indoor match.
The archetypal reaction is the alkaline hydrolysis of ethyl benzoate (R=R'=H) in a water/ethanol mixture at 30 °C. Measurement of the reaction rate k 0 combined with that of many substituted ethyl benzoates ultimately result in a reaction constant of +2.498.
