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313.15、323.15、333.15、343.15 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 practi-cal data.The hydrophobicity and viscosity reduction of[A336]FeCl4 iron-based ions are ben-eficial 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.
