摘要
New experimental data are presented for the solubility of hydrogen sulfide in the ionic liquid 1-N-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) at five temperatures in the range (298-403) K at pressures up to 9.6 MPa. The ionic liquid [bmim][PF6] is a good solvent for hydrogen sulfide. At 9 MPa the mole fraction H2S in the liquid is about 0.7. The solubility is a strong function of temperature; at 2 MPa the solubility (mole fraction H2S) decreases from about 0.84 at 298 K to about 0.2 at 403 K. The Krichevsky-Kasarnovsky equation was used to correlate the experimental data, and Henry's constants were obtained. The solution thermodynamic properties at standard temperature and pressure were calculated.
