Zinc → Zinc trifluoromethanesulfonate

Participants

Reaction Steps

0.5 g of zinc 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 22.2 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 zinc triflate obtained may then be isolated by eliminating the excess zinc by filtration and evaporating the water at 100° C. under atmospheric pressure. In this way, one recovers 3 g of zinc triflate, having the formula Zn(CF3SO3)2, in the form of a white powder.
