中文摘要:

      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][Tf2N]）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][Tf2N]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%。

英文摘要:

      The solubilities of R1234yf in 1-Hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([HMIM][Tf2N]) at temperatures from 293K to 353K and at pressures from 99 kPa to 925 kPa were measured using the isochoric saturation method. The uncertainties of temperature, pressure and solubility are 0.02K, 0.3 kPa, 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.
