Cu(I)-containing room temperature ionic liquids as selective and reversible absorbents for propyne |
| 초록 |
Cu(I)-containing room temperature ionic liquid (Cu-RTIL), prepared from CuCl and 1,3-dimethylimidazolium methylphosphite ([DMIM][MeHPO3]), was found to reversibly and selectively interact with propyne over propylene. Cu-RTIL exhibited 12 times higher propyne absorption capacity and 14 times higher ideal propyne/propylene selectivity than [DMIM][MeHPO3]. FAB-mass spectral and computational results with Cu-RTIL (CuCl/[DMIM][MeHPO3]=1/2) strongly imply that the Cu-RTIL contains stable methylphosphite-coordinated anionic Cu(I) species such as CuCl(MeHPO3)- and Cu(MeHPO3)2-. Computational studies on the optimized structures demonstrate that the preferential absorption of propyne over propylene in a Cu-RTIL. |
