A Novel Synthetic Process for the Preperation of Brominated Pyruvic Acid
HUANG Zi-han1, SHAO Guo-guang1*, HU Neng2 (1. NO. 21 Middle School of Changsha, Changsha 410000, China; 2. Changsha University of Science and Engineering, College of Chemical and Biological Engineering, Changsha 410114, China)
Abstract:Brominated pyruvic acid is an important intermediate, which is synthesized using pyruvic acid and dibromohydantoin as the raw materials. The yield of brominated pyruvic acid is of 40% under the optimum conditions including reaction temperature of 50℃, p-toluene sulphonic acid as catalyst, and methanol as solvent. This novel process has advantages of friendly operation and simple post-processing.
Key words:pyruvic acid; dibromohydantoin; brominated pyruvic acid
