Used in many chemical processes as starting materials or as reaction intermediates., Bromoacetici acid is an industrial and laboratory chemical. It is produced as a drinking water disinfection by-product and small amounts may be found in treated drinking water., Methods of Manufacturing: Bromoacetic acid can be prepared by the bromination of acetic acid in the presence of acetic anhydride and a trace of pyridine, by the Hell-Volhard-Zelinsky bromination catalyzed by phosphorus, and by direct bromination of acetic acid at high temperatures or with hydrogen chloride as catalyst. Other methods of preparation include treatment of chloroacetic acid with hydrobromic acid at elevated temperatures, oxidation of ethylene bromide with fuming nitric acid, hydrolysis of dibromovinyl ether, and air oxidation of bromoacetylene in ethanol., By heating acetic acid and bromine., Bromoacetic acid, is, ... usually prepared by the well-known Hell-Volhard-Zelinski reaction in which the alpha-hydrogens of the carboxylic acid are replaced by bromine. A catalyst, such as a phosphorus trihalide, is necessary to convert the acid to the acid halide, the actual reaction intermediate. If the acid chloride or bromide is available as a starting material, no catalyst is needed and only one equivalent of bromine is required versus the two equivalents necessary when the carboxylic acid is the starting material. The resulting bromoacetyl halide can either be hydrolyzed or esterified to produce bromoacetic acid or its esters., U.S. Production: Production volumes for non-confidential chemicals reported under the Inventory Update Rule.
