Procedure

Trifluoromethanesulfonimide ((CF3SO2)2NH, hereinafter HTFSI) was dissolved in water to make a 1 mol/l (1M) solution. Calcium carbonate (CaCO3) was added to the solution with stirring to a molar ratio of 2:1 (HTFSI:CaCO3). A reaction of calcium carbonate and HTFSI produced calcium bistrifluoromethanesulfonimide, carbon dioxide and water as shown below: CaCO3+HTFSI=Ca(TFSI)2+CO2+H2O
