Abstract

A process for producing a sulfamyl fluoride composition includes providing a solution comprising fluorosulfonic acid, urea and a solvent; reacting the solution at a reaction temperature from 80° C. to about 170° C. to produce a mixture including sulfamyl fluoride, bis(fluorosulfonyl) imide, ammonium fluorosulfate and the solvent; separating the ammonium fluorosulfate from the mixture; and separating the mixture into a sulfamyl fluoride composition and a recycle composition, the sulfamyl fluoride composition including a higher concentration of sulfamyl fluoride and bis(fluorosulfonyl) imide than the recycle composition. A mole ratio of the fluorosulfonic acid to the urea in the solution is from about 1.80:1 to about 2.00:1.

Claims (10)

1. A composition comprising:

sulfamyl fluoride; and

bis(fluorosulfonyl) imide, wherein a concentration of the sulfamyl fluoride is from about 2 mole percent to about 10 mole percent of a combination of the sulfamyl fluoride and the bis(fluorosulfonyl) imide.

2. The composition of claim 1 , wherein the concentration of the sulfamyl fluoride is from about 2 mole percent to about 9 mole percent of the combination of the sulfamyl fluoride and the bis(fluorosulfonyl) imide.

3. The composition of claim 1 , wherein the concentration of the sulfamyl fluoride is from about 3 mole percent to about 8 mole percent of the combination of the sulfamyl fluoride and the bis(fluorosulfonyl) imide.

4. The composition of claim 1 , wherein the concentration of the sulfamyl fluoride is from about 4 mole percent to about 8 mole percent of the combination of the sulfamyl fluoride and the bis(fluorosulfonyl) imide.

5. The composition of claim 1 , wherein the concentration of the sulfamyl fluoride is from about 3 mole percent to about 9 mole percent of the combination of the sulfamyl fluoride and the bis(fluorosulfonyl) imide.

6. The composition of claim 1 , wherein the concentration of the sulfamyl fluoride is from about 2 mole percent to about 8 mole percent of the combination of the sulfamyl fluoride and the bis(fluorosulfonyl) imide.

7. The composition of claim 1 , wherein the concentration of the sulfamyl fluoride is from about 3 mole percent to about 6 mole percent of the combination of the sulfamyl fluoride and the bis(fluorosulfonyl) imide.

8. The composition of claim 1 , wherein the concentration of the sulfamyl fluoride is from about 4 mole percent to about 7 mole percent of the combination of the sulfamyl fluoride and the bis(fluorosulfonyl) imide.
