The solubility parameters of four imidazolyl acetate ionic liquids were determined by inverse gas chromatography in the range of 353. 15-393. 15 K. The results show that the solubility parameter values of the four ionic liquids decrease linearly with the increase of temperature in the experimental temperature range. The solubility parameters of the four ionic liquids are 26. 14, 24. 38, 23. 60 and 23. 04 MPa1/2 at 333. 15 K by extrapolation method. The solubility parameters of the ionic liquid were also simulated by Hansen solubility parameter software at 333. 15 K. The simulation results are 26. 52 , 23. 99 , 23. 45 and 22. 00 MPa1/2 respectively. The results obtained by the two methods are consistent with each other in the error rang of +/- 1. 05 MPa1/2, indicating that the two methods are applicable to the determination of the solubility parameters of imidazolyl acetate.
