| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Use | for organic synthesis. As brominating agent, oxidant, Catalyst. |
| production method | is obtained by reacting acetamide with bromine. The acetamide was dissolved in molar liquid bromine and after cooling to 4-5 °c, the pre-cooled potassium hydroxide solution was added with stirring. The resulting semi-solid was placed at 0-5 °c for 2-3H. Sodium chloride and chloroform were added to the reaction mixture, and after stirring and heating, the chloroform solution was decanted from the solid matter, and extracted twice more with chloroform. The extract was dried over anhydrous sodium sulfate and filtered. The crystals were precipitated by addition of ethane, cooled, filtered, washed with hexane, and dried to obtain N-bromoacetamide. The yield was about 50%. |
