Procedure
43.9 g. of the barium trifluoromethanesulfonate are dissolved in 200 ml of water. To the stirred solution, there are added at room temperature, 22.2 g. of aluminum sulfate dissolved in 150 ml of water. The reaction mixture is then gently heated to 50°-60° C. for 0.5 hours. The warm mixture is then filtered, the filtrate decolorized with charcoal, refiltered and evaporated at reduced pressure and 60° C. to a viscous residue, then dried with a vacuum pump at 50°. The solid residue is collected, grinded and placed in a dessicator over sulfuric acid and under vacuum. The solid analyzed for 4.66% Al and 15.85% S, thus indicating a ratio Al:CF3SO3 of 1:2.87. Yield 25.2 g.
