合成了4种1-甲基-3-烷基咪唑四氯化铁盐[C_nmim]FeCl_4(n=2,4,6,8)及3种1-甲基-3-丁基咪唑四卤化铁 ([C_4mim]FeX_4,X=Cl, Br)磁性离子液体, 光谱结果表明, [C_nmim]FeCl_4及[C_4mim]FeBr_4中阴离子单一, 而[C_4mim]FeClBr_3及[C_4mim]FeCl_3Br中的阴离子为FeBr_4~-, FeBr_3Cl~-, FeCl_2Br_2~-, FeCl_3Br~-, FeCl_4~-的混合物.测定了其密度、粘度、电导率, 磁性离子液体密度较大, 25℃时为1.25~1.94 g/cm~3; 粘度较小, 25℃时为21~65 mPa·s; 电导率较大, 30℃时为0.23~1.37 S/m.并研究了其物性随温度及结构的变化规律 |

Seven magnetic ionic liquids of 1-methyl-3-alkylimidazolium tetrachloroferrate[C_nmim]FeCl_4(n=2,4,6,8)and 1-methyl-3-butylimidazolium tetrahalogenoferrate[C_4mim]FeX_4(X=Cl, Br)were synthesized and verified with ~1H-NMR, Raman and MS spectra.[C_nmim]FeCl_4 and [C_4mim]FeBr_4 had single anions, but[C_4mim]FeClBr_3 and [C_4mim]FeCl_3Br had multi-anions, including FeBr_4~-, FeBr_3Cl~-, FeCl_2Br_2~-, FeCl_3Br~- and FeCl_4~-.The density, viscosity and conductivity of magnetic ionic liquids were measured. It was found that their densities were bigger than those of traditional ionic liquids,1.25~1.94 g/cm~3 at 25℃;viscosities were lower,21~65 mPa-s at 25℃;conductivities were higher,0.23~1.37 S/m at 30℃.The influences of temperature and structure of cations and anions on the above properties were extensively investigated |
