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.

Benzoic acid is cheap and readily available, so the laboratory synthesis of benzoic acid is mainly practiced for its pedagogical value. It is a common undergraduate preparation. Benzoic acid can be purified by recrystallization from water because of its high solubility in hot water and poor solubility in cold water. The avoidance of organic ...
The Prévost reaction is a chemical reaction in which an alkene is converted by iodine and the silver salt of benzoic acid to a vicinal diol with anti stereochemistry. [1] [2] [3] The reaction was discovered by the French chemist Charles Prévost (1899–1983). The Prévost reaction
It reacts with water to produce hydrochloric acid and benzoic acid: C 6 H 5 COCl + H 2 O → C 6 H 5 COOH + HCl. Benzoyl chloride is a typical acyl chloride. It reacts with alcohols to give the corresponding esters. Similarly, it reacts with amines to give the amide. [5] [6]
Benzoic acid was shown to be genotoxic in vitro. [22] Benzoic acid therefore might have a role in benzotrichloride carcinogenicity, but benzotrichloride has more carcinogenic potential than benzoic acid, suggesting that an intermediate in hydrolysis is responsible for at least part of the carcinogenicity. [1]
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]
He remembered one time where Marines helped local Afghans build a school, near Combat Outpost San Diego, outside Marjah. “And all the kids went to that school, and the Taliban came over and splashed acid in their faces and, like, horribly deformed them,” he said. “And it was because they went to a school that we built and they didn’t ...
Ammonium benzoate, a white powder-like substance, is the ammonium salt of benzoic acid. [1] This compound is prepared by the reaction of benzoic acid and ammonia.
