Reaction Conditions

Reaction Steps

A 500 mL reactor was charged with 65 g (93% purity, 0.194 mole/1.0 equivalent) of triethylammonium 1,1,2,2-tetrafluoro-4-hydroxy-butane-1-sulfinate obtained in Example 2-1 by purification, 200 g of water and 46 g (0.40 mole/2.1 equivalents) of 30% hydrogen peroxide at room temperature, followed by 6 hours of stirring at 40° C. Upon confirming the termination of the reaction, the reaction liquid underwent cooling, and 7.5 g of sodium sulfite was added to the reaction liquid, followed by stirring. Thereafter, 350 g of acetone was added to a liquid obtained by distilling the solvent out of the reaction liquid, followed by 1 hour of stirring at room temperature. Thereafter, filteration was performed in the use of a filter paper. An obtained filtrate was concentrated and dried, thereby obtaining 65.6 g of a target triethylammonium 1,1,2,2-tetrafluoro-4-hydroxy-butane-1-sulfonate. It exhibited a purity of 92% and a yield of 95% at this time.
