The major cause of benzene in soft drinks is the decarboxylation of benzoic acid in the presence of ascorbic acid (vitamin C, E300) or erythorbic acid (a diastereomer of ascorbic acid, E315). Benzoic acid is often added to drinks as a preservative in the form of its salts sodium benzoate (E211), potassium benzoate (E 212), or calcium benzoate ...
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.
In some places, such as the United States, all the water supplied to residences by utilities must meet primary (health-based) drinking water standards. Regulations may require large-scale treatment systems to remove arsenic from the water supply. The effectiveness of any method depends on the chemical makeup of a particular water supply.
Benzotrichloride is a poorly water-soluble, clear to yellowish liquid with a penetrating odor. It hydrolyzes rapidly to benzoic acid and hydrochloric acid with a half life of about 2.4 minutes, thus making the compound unstable in the presence of water. [2]
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]
Although the maximum rate of biotransformation of benzoic acid to hippuric acid varied between 17.2 and 28.8 mg.kg-1.h-1 among the six individuals, the mean value (23.0 mg.kg-1.h-1) was fairly close to that provided by daily maximum dose (0.5 g.kg-1.day-1) recommended in the treatment of hyperammonaemia in patients with inborn errors of ureagenesis
Across a sample of 23 nicotine salts available for public purchase, the three most common acids used in the formation of nicotine salts were lactic acid, benzoic acid and levulinic acid. [8] Benzoic acid is the most used acid to create a nicotine salt. [9] Nicotine pyruvate is another form of nicotine salt. [10] A chemical reaction with a ...
Halazone (4-(dichlorosulfamoyl)benzoic acid) is a chemical compound whose formula can be written as either C 7 H 5 Cl 2 NO 4 S or (HOOC)(C 6 H 4)(SO 2)(NCl 2). It has been widely used to disinfect drinking water. Other names for this compound include p-sulfondichloramidobenzoic acid, 4-[(dichloroamino)sulfonyl]benzoic acid, and Pantocide.
