Procedure

Lanthanum carbonate (15 g.) and trifluoromethanesulfonic acid (22.5 g) are combined as described in Example II. The solution is evaporated at reduced pressure and the residue, dried over sulfuric acid in dessicator. The product obtained, 20.4 g., gave the following analysis: % La 22.06; % S 15.88; % H2O 5.61, indicating an Al:S ratio of 1:3.12.
