Yield:2926-30-9 1100 g
Reaction Conditions:
with sodium hydroxide;calcium oxide in water; under 1500.15 - 7500.75 Torr; for 9.5 h;
Steps:
3; 5 Example 3
875 g of a 32.0% aqueous solution of sodium hydroxide, 424 g of calcium oxide and 580 g of high purity water were successively added to a 316L stainless steel reaction vessel, and the temperature was raised to 85 ° C and the mixture was stirred for 3 hours. Then, the trifluoromethane sulfonyl fluoride gas was continuously introduced into the reaction vessel, Controlling the reaction pressure to be between 0.2 MPa and 1.0 MPa; stopping the ventilation when the mass of ventilation is 980 g of trifluoromethanesulfonyl fluoride, the ventilation time is 4 hours, then keeping the reaction for 2.5 hours, then lowering the temperature to 25 DEG C; The filtrate was filtered to obtain an aqueous solution of sodium trifluoromethanesulfonate. The concentration of sodium trifluoromethanesulfonate was 47.55%, pH = 14, F = 7 ppm, and ICP was 0.5 ppm and 0.14 ppm respectively. Fluoride ion concentration <10ppm, Fe <1ppm, Ni <1ppm, indicating that the reaction of 316L stainless steel corrosion, the method greatly reduces the corrosion of equipment, equipment can greatly extend the service life and maintenance costs.
