ETHANESULFINICACIDSODIUMSALT Use and Manufacturing
To a 4-neck flask, sodium sulfite (53.9 g), sodium hydrogen carbonate (65.34 g), and water (325 ml) were added at room temperature under nitrogen atmosphere. After the mixture was stirred at 80° C. for 1 .3 hours, ethanesulfonyl chloride (50.0 g) was add thereto, and the mixture was then stirred for an additional 4.2 hours. The reaction mixture was concentrated, and to the resulting residue was added ethanol, and the mixture was thrther concentrated. To the resulting residue was added toluene, and the mixture was concentrated and the resulting solid was dried, and then thereto was added ethanol (100 ml), and the mixture was heated under reflux. The resulting mixture was filtered and washed with ethanol. The filtrate and wash solution were combined and concentrated to give 38.96 g of sodium ethanesulfinate.Dimethyl disulphide (0.45 g, 4.8 mmol) was dissolved in dry methyiene chloride (5 ml) and a solution of sulfuryl chloride (0.65 g, 4.8 mmol) in dry methylene chloride (5 ml) added dropwise. Upon completion of the addition, the reaction mixture was refluxed for 0.5 h. A solution of the mixture of
