In this paper, new data for the solubilities and diffusion coefficients of difluoromethane (R32), fluoroethane (R161) and 1,1-difluoroethane (R152a) in ionic liquid 1-hexyl-3-methylimidazolium tris(pentafluoroethyl)trifluorophosphate ([HMIM][FEP]) at temperatures ranging from 293 K to 343 K and at pressures up to 0.5 MPa were presented. The solubilities of R32, R161 and R152a in [HMIM][FEP] can be improved by decreasing the temperature and increasing the pressure. With the increasing temperature, the diffusion coefficients and Henry's law constants of the three hydrofluorocarbons increase. The solubilities and diffusion coefficients of R32, R152a, and R161 in [HMIM][FEP] were correlated well with the NRTL equation and the Wilke-Chang equation, respectively.

本文研究了二氟甲烷（R32），氟乙烷（R161）和1,1-二氟乙烷（R152a）在离子液体1-己基-3-甲基咪唑三（五氟乙基）三氟磷酸盐（[HMIM]）中的溶解度和扩散系数的新数据[FEP]）的温度范围为293 K至343 K，压力最高为0.5 MPa。R32，R161和R152a在[HMIM] [FEP]中的溶解度可通过降低温度和增加压力来提高。随着温度的升高，三种氢氟烃的扩散系数和亨利定律常数增加。R32，R152a和R161在[HMIM] [FEP]中的溶解度和扩散系数分别与NRTL方程和Wilke-Chang方程密切相关。
