Air-liquid interfacial tension data were determined experimentally for five 1-Cn-3-methylimidazolium based ionic liquids (n=2, 4, and 6), three with trifluoromethanesulfonate and two with tetrafluoroborate anion, at atmospheric pressure in the temperature range from 268 to 356 K. The accuracy of the results was confirmed by employing the Wilhelmy plate and the du Nouy ring methods in parallel, using the Kruss K100MK2 tensiometer. For the Wilhelmy plate data the combined standard uncertainty is estimated to be about 0.05 mN/m.
