摘要/Abstract

摘要：

采用恒定容积法在温度范围308.15~328.15 K、压力范围0~3 MPa条件下测定了CO₂在碳酸二乙酯（DEC）、离子液体[Bmim][NTf₂]以及二者不同质量分数配比混合溶剂中的溶解度，并用COSMO-RS模型研究了离子液体的加入对DEC蒸气分压的影响。实验表明，在相同实验条件下CO₂在[Bmim][NTf₂]中的溶解度大于在DEC中的溶解度。[Bmim][NTf₂]的加入可强化CO₂在DEC中的溶解性能，在相同温度下CO₂在混合溶剂中的溶解度随[Bmim][NTf₂]质量分数增加而增大，在相同浓度的混合溶剂中CO₂的溶解度随温度升高而降低。COSMO-RS模型计算表明，DEC的蒸气分压下降的分数随混合溶剂中离子液体质量分数增加而增大，而对于相同质量分数配比的混合溶剂温度对DEC的蒸气分压影响较小。

Abstract:

CO₂ solubility in diethyl carbonate (DEC), ionic liquid 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide ([Bmim] [NTf₂]), and their mixtures at various mass ratio were measured isovolumetrically at temperature of 308.15-328.15 K and pressure of 0-3 MPa. Effect of[Bmim] [NTf₂] on DEC vapor pressure was studied using COSMO-RS model. The experimental results showed that CO₂ solubility in DEC and[Bmim] [NTf₂] increased with increasing pressure at constant temperature but decreased with increasing temperature at constant pressure. CO₂ solubility in DEC was lower than that in[Bmim] [NTf₂] under same conditions, which could be enhanced by adding[Bmim] [NTf₂] to DEC. CO₂ solubility in mixture of[Bmim] [NTf₂] and DEC increased with increasing mass ratio of[Bmim] [NTf₂] at constant temperature while CO₂ solubility in mixtures of constant mass ratios decreased with increasing temperature. COSMO-RS simulation showed that percentage of DEC vapor pressure drop increased with increasing mass ratio of[Bmim] [NTf₂] whereas DEC vapor pressure changed a little at temperature of 308.15-328.15 K for mixtures of same mass ratio.
