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. It is a colorless liquid that is almost insoluble in water, but miscible with most organic solvents.
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.

The synthesis of methyl benzoate by Fischer–Speier esterification. Fischer esterification or Fischer–Speier esterification is a special type of esterification by refluxing a carboxylic acid and an alcohol in the presence of an acid catalyst. The reaction was first described by Emil Fischer and Arthur Speier in 1895. [1]
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]
The reaction produces benzyl benzoate. [4] The Tishchenko reaction: benzaldehyde reacts to benzyl benzoate, the catalyst is sodium benzylate. Enolizable aldehydes are not amenable to Claisen's conditions. Vyacheslav Tishchenko discovered that aluminium alkoxides allowed the conversion of enolizable aldehydes to esters.
President Donald Trump campaigned on the promise of tariffs. He followed through on that pledge within days of re-taking office, making many Americans concerned about their already-strained ...
Transesterification is the process of exchanging the organic functional group R″ of an ester with the organic group R' of an alcohol.These reactions are often catalyzed by the addition of an acid or base catalyst. [1]
Things went south as soon as the procedure started: After several failed attempts at numbing her gums, Reynoso was forced to power through in agony, gripping the arms of her chair to endure the pain.
