| Summary: | The interaction between β-cyclodextrin and ionic liquid 1-butyl-3-methylimidazolium
tetrafluoroborate ([Bmim][BF4]) had been studied. The inclusion complexation interaction
was confirmed by FT-IR spectra. The inclusion complex was also characterized by 1H NMR,
TGA and DSC. The results showed that the host-guest system presented a channel type
structure and each glucose unit of β-cyclodextrin was in similar environment. The
decomposition temperature of inclusion complex was lower than that of [bmim][BF4] and β-
cyclodextrin individually. The ratio of 1:1 inclusion complex was determined in this study. |
