摘要: 在温度为31315~35815 K范围下对铁基离子液体\[A336\]FeCl4与水分层后的离子液体相密度和黏度进行了测量。采用经验关联式对密度和黏度数据进行了拟合,并与纯离子液体进行了比较。\[A336\]FeCl4铁基离子的疏水性和黏度的降低有利于湿法氧化脱硫过程。分别在31315323153331534315 K温度条件下测定了0~150 kPa压力范围内硫化氢在铁基离子液体\[A336\]FeCl4中的溶解度数据,使用RETM模型对溶解度数进行拟合,相关系数大于099。得到了\[A336\]FeCl4吸收硫化氢的亨利系数和化学平衡常数,为进一步研究其在气体脱硫中的应用提供了依据。

Abstract: The ionic liquid density and viscosity of the iron-based ionic liquid \[A336\]FeCl4 layered with water were measured at temperatures ranging from 31315 K to 35815 K. Density and viscosity data were fitted using empirical correlations, and compared with practical data. The hydrophobicity and viscosity reduction of \[A336\]FeCl4 iron-based ions are beneficial to the wet oxidative desulfurization process. The solubility of hydrogen sulfide in iron-based ionic liquid \[A336\]FeCl4 in the pressure range of 0—150 kPa were measured at 31315, 32315, 33315 and 34315 K, respectively. The solubility was fitted by RETM model. The correlation coefficient is greater than 099. The Henry′s coefficient and the chemical equilibrium constant for the absorption of hydrogen sulfide by \[A336\]FeCl4 were obtained. This work provides a basis for further research on application of \[A336\]FeCl4 in gas desulfurization.
