In the present study, new ionic liquids (ILs) such as task specific ionic liquids (TSILs), polymerized ionic liquids (PILs), and amino acid-based polymerized ionic liquids (AAPILs) were synthesized and their efficiency for capturing CO2 was studied. Nitrile imidazolium-based TSILs with different alkyl chain length and different anion ([DDS], [TFMS], [SBA], [BS], [DOSS]), PILs consisting of [VBTMA]
在本研究中,新的离子液体(IL),诸如任务特定的离子液体(功能化离子液体),聚合的离子液体(比尔森)和(AAPILs)的合成基于氨基酸的聚合的离子液体和它们的用于捕获CO效率2进行了研究。具有不同烷基链长度和不同阴离子([DDS],[TFMS],[SBA],[BS],[DOSS])的腈基咪唑基TSIL,由[VBTMA],[VBTEA]和[METMA]阳离子组成的PIL合成了[BF 4 ],[Cl],[NO 3 ],[PF 6 ]和[TFMS]阴离子以及掺入了[VBTMA]作为阳离子和[Arg],[Pro]作为阴离子的AAPIL。结果表明,随着烷基链长度的增加,CO 2的吸附增加,[C 2 CNDim] [DOSS]的CO最高。TSIL中有2种吸附,在10 bar,298 K时达到0.55 mol分数。在聚合离子液体中,聚合物形式的CO 2吸附能力比单体形式增加。为了提高PIL吸附CO 2的
