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.
