| titleOfInvention | Production of dibromonitro compound |
| abstract | PURPOSE: To obtain the titled substance useful as pharmaceuticals and disinfectants, etc., safely in high yield and purity, by using formaldehyde or acetaldehyde as a raw material at a specific ratio to nitromethane, condensing the raw materials using an alkali, and brominating the product with bromine without separating from the reaction system. n CONSTITUTION: 1mol of nitromethane and ≥1.5mol of formaldehyde or acetaldehyde are dissolved in a solvent and condensed with an alkali such as sodium hydroxide, potassium methoxide, etc. The condensation product is, without separating from the reaction system, brominated with bromine to obtain the compound of formula (R is H or methyl). The solvent used in the above reaction is water, lower alcohol, toluene, etc., and the condensation reaction is carried out at -20W+120°C. Bromine may be used as it is in the bromination reaction, however, it is preferable to dissolve bromine in a solvent and add the solution dropwise to the reaction system. The amount of bromine is generally ≥2 equivalent based on nitromethane. n COPYRIGHT: (C)1986,JPO&Japio |
