Trifluoromethanesulfonic acid → Aluminum trifluoromethanesulfonate

Participants

Reaction Steps

0.2 g of aluminium powder and 70 ml of water are introduced with stirring into a 250-ml glass flask. The suspension obtained is brought to 80° C., then 33.3 ml of an aqueous solution of 0.57N triflic acid is added drop by drop. This mixture is maintained with stirring at 80° C. for 2 hours, then at ambient temperature for 48 hours. The aluminium triflate obtained may then be isolated by eliminating the excess aluminium by filtration and evaporating the water at 100° C. under atmospheric pressure. In this way one recovers 3.5 g of aluminium triflate, having the formula Al(CF3SO3)3, in the form of a white powder.
