Claims
- 1. A composition comprising sulfonyl amide salts of which said salts are at least 50 mol-% sulfonyl amide salts represented by the formula (RSO2NMb)3-bM′c wherein R is aryl, fluoro-aryl, or XCF2— where X is H, halogen, fluorinated or non-fluorinated linear or cyclic alkyl radicals having 1-10 carbons, whereof one or more said carbons may optionally be replaced by ether oxygen, M′ is an alkaline earth metal, b=1, or 2, c=0 or 1, M is alkaline earth or alkali metal when b is 1 or 2 respectively and c=0, and M is alkali metal when b=1, and c=1, with the proviso that c 1 when b=2.
- 2. The composition of claim 1 wherein at least 90 mol-% of said sulfonyl amide salts are represented by the formula (RSO2NMb)3-bM′c.
- 3. The composition of claim 1 wherein R is perfluoroalkyl.
- 4. The composition of claim 3 wherein R is trifluoromethyl.
- 5. The composition of claim 1 wherein M is Na and b=2.
- 6. A process for forming a sulfonyl amide salt, the process comprisingcombining in an atmosphere having a water vapor concentration of less than 50 parts per million at least one alkali or alkaline earth hydride, a sulfonyl amide or monometal sulfonyl amide salt thereof having the formula (RSO2NH)3-aM″ (II) wherein a=1 or 2, M″ is alkaline earth metal when a=1, M″ is alkali metal or hydrogen when a=2, and R is aryl, fluoro aryl, fluoro-aryl, of XCF2— where X is H, halogen, or a fluorinated or non-fluorinated linear or cyclic alkyl radical having 1-10 carbons , whereof one or more said carbons may optionally be replaced by ether oxygen; andan aprotic liquid comprising acetonitrile, wherein the acetonitrile is substantially free of water,thereby forming a reaction mixture; and, reacting said reaction mixture forming a precipitate of (RSO2NMb)3-bM′c; andseparating said precipitate from said liquid.
- 7. The process of claim 6 wherein the hydride is sodium hydride.
- 8. The process of claim 6 wherein R is perfluoroalkyl.
- 9. The process of claim 9 wherein R is trifluoromethyl.
- 10. The process of claim 6 further comprising the step of heating the mixture to a temperature in the range of room temperature to 60° C.
- 11. The process of claim 6 wherein the conversion is at least 90 mol %.
- 12. The process of claim 6 wherein M″ is H.
- 13. The process of claim 6 wherein the aprotic liquid and the (RSO2NH)3-aM″ are mixed to form a solution at the same time as or prior to the addition of the hydride.
