摘要：
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 H-2 in [hmim][Tf2N] is low and increases toward higher temperatures. For example, at T approximate to 293 K (413 K) and p approximate to 9 MPa, only about 0.106 mol (0.170 mol) of the gas is dissolved in 1 kg of the ionic liquid.
