Procedure

40 ml of H2O are placed in a 100 ml round-bottomed flask having a magnetic stirrer, and 12.78 g (85 mmol) of trifluoromethanesulfonic acid are weighed in. With stirring, 14.15 g (15 mmol) of lanthanum carbonate are added. The neutral suspension is filtered, and the filtrate is concentrated by evaporation in a rotary evaporator and then dried under a high vacuum. 18.0 g of lanthanum triflate are obtained in the form of a white powder.
