Abstract:

The halogenated hydrocarbon and pyridine are used in the synthesis of room temperature ionic liquid intermediates bromided N-heptyl pyridine HEPB, and the nuclear magnetic resonance instrument and the intermediate infrared spectrometer are used in chemical structure characterization, so it is determined that the synthesis is the room temperature ionic intermediates HEPB. We use differential scanning calorimetric method for the determination of HEPB melting point and enthalpy change. We use the double decomposition reaction of HEPB and NaBF4 in acetone for the synthesis of HEP-BF4 ionic liquids. We use infrared spectrometer for the structure characterization, it is proved that we have gotten HEP-BF4 room temperature ionic liquids. Solvent polarity and acid alkali both will have an influence on ultraviolet spectrum diagram displacement of room temperature ionic liquid, so in the research of ultraviolet spectrum diagram of ionic liquids and other solvent mixed solution, it is necessary to indicate which solvent is used.
