2-BROMOETHANESULPHONIC ACID, NA SALT - Uses and synthesis methods
application
Sodium bromoethyl sulfonate can be used as a pharmaceutical intermediate and an organic synthesis intermediate, and can be used in the laboratory research and development process and the chemical and pharmaceutical production process.
production method
To the mixture of 1, 2-dibromoethane, ethanol and water heated to boiling, drop an aqueous solution of anhydrous sodium sulfite, continue to reflux for 2h after adding, and then evaporate ethanol and unreacted 1, 2-dibromoethane. Ethanol is added to the above distillation residue to extract sodium 2-bromoethanesulfonate from sodium bromide and unreacted sodium sulfite. During extraction, the mixture is boiled, and the extract is cooled to crystallize 2-bromoethanesulfonate. Sodium, the yield is 78-90%.
