摘要 采用动态法测定苄嘧磺隆在超临界CO2中的平衡溶解度,所用的压力范围为10~35MPa,温度为308.15、318.15、328.15K,结果表明其溶解度摩尔分数为4.13×10-7~1.932×10-6。实验数据经Chrastil密度型模型和Chrastil改进模型模拟,均取得较好的吻合。后者的模拟效果稍优于前者,模拟所得的平均相对偏差为8.82%,根均平方为11.30%,两者很接近,这表明理论模型的可操作性很好。 The equilibrium solubility of bensulfuron-methyl in the supercritical CO2 was measured by using a dynamic method at pressures between 10 and 35 MPa, at temperatures of 308.15, 318,15, 328.15 K. The result showed that the molar fraction of bensulfuron-methyl solubility is in the range of 4.13× 10^-7-1.932× 10^-6. And the experimental data well correlated with the empirical density-based Chrastil model and the empirical improved Chrastil model. The latter excelled the former at simulation. The AARD was 8,82% and the RMS was 11.30%. Both of them were close to each other, which showed the maneuverability of model was good.
