摘要

A series of 20 dual aminofunctionalised phosphonium ionic liquids,(3-aminopropyl)tributylphosphonium amino acid salts ([aP4443][AA], in which [AA]=[Ala], [Arg], [Asn],[Asp], [Cys], [Gln], [Glu],[Gly],[His], [Ile], [Leu], [Lys], [Met],[Phe], [Pro], [Ser],[Thr], [Trp],[Tyr] and [Val]), has been prepared.Their physicochemical properties, such as density, viscosity, glass transition and thermal decomposition temperatures and conductivity, have been determined.In particular, the [aP4443][AA]ionic liquids (ILs) have low glass transition temperatures ranging from 69.7to 29.6 8C and high decomposition temperatures (all above 200 8C). The effects of the variation of the structure of [AA] on the above physicochemical properties are discussed. Furthermore,the CO2 absorption of [aP4443]- ACHTUNGTRENUNG[Gly], [aP4443]ACHTUNGTRENUNG[Ala], [aP4443]ACHTUNGTRENUNG[Val] and[aP4443]ACHTUNGTRENUNG[Leu], taken as examples, was investigated. It was found that the supportedabsorption of CO2 by the[aP4443][AA] ILs almost reaches equilibrium within 80 min, the chemical absorption of CO2 by the [aP4443][AA]ILs approaches 1 mol CO2 per mol ionic liquid (twice that reported before) and the [aP4443][AA] ILs can be repeatedly recycled for CO2 uptake.
