摘　　要：基于等体积饱和法测量了温度在293.0~353.0K、压力在99.0~925.0kPa时R1234yf在离子液体1-己基-3-甲基咪唑双三氟甲磺酰亚胺盐([HMIM][Tf_2N])中的溶解度,温度、压力、溶解度的测量不确定度分别为0.02K、0.3kPa、3%。利用改进的Krichevsky-Kasarnovsky方程和NRTL方程对R1234yf在[HMIM][Tf_2N]中的溶解度进行了关联,计算值与实验值之间的相对偏差绝对平均值均为0.7%,最大相对偏差均小于1.9%。The solubilities of R1234yf in 1-Hexyl-3-methylimidazolium bis（trifluoromethylsulfonyl）imide（[HMIM][Tf2N]）at temperatures from 293Kto 353Kand at pressures from 99kPa to 925kPa were measured using the isochoric saturation method.The uncertainties of temperature,pressure and solubility are 0.02K,0.3kPa,3%,respectively.A modified Krichevsky-Kasarnovsky equation and NRTL equation were used to model the solubilities of R1234yf in[HMIM][Tf2N].The modified Krichevsky-Kasarnovsky equation and NRTL equation agree well with the experimental data.The AAD and MD between the experimental data and the calculated values are less than 0.7%and 1.9%,respectively.
