ABSTRACT
New experimental results are presented for the solubility of hydrogen in the ionic liquid 1-hexyl-3- methylimidazolium bis(trifluoromethylsulfonyl)imide ([hmim][Tf2N]) for temperatures from (293 to 413) K and pressures up to about 10 MPa. The extended Henry s law is applied to correlate the solubility pressures. The solubility of H2 in [hmim][Tf2N] is low and increases toward higher temperatures. For example, at T = 293 K (413 K) and p = 9 MPa, only about 0.106 mol (0.170 mol) of the gas is dissolved in 1 kg of the ionic liquid.
