Procedure
The trace amount of trifluoromethane sulfonic acid monohydrate in the non-aqueous, cyclohexane-rich phase is neutralized with calcium hydroxide to produce calcium trifluoromethane sulfonate, which is filtered from the finished product. The calcium trifluoromethane sulfonate can be converted to trifluoromethane sulfonic acid monohydrate and the recovered trifluoromethane sulfonic acid monohydrate reused.
