Double Decomposition

The halogenated hydrocarbon and pyridine are used in the synthesis of room temperature ionic liquid intermediates chlorinated N-butyl pyridine BPC. We use the double decomposition reaction of BPC and NaNO3in acetone for the synthesis of BP-NO3 ionic liquids. We use infrared spectrometer for the structSubscript texture characterization, it is proved that we have gotten BP-NO3room temperature ionic liquids. Solvent polarity and acidSubscript textalkali both will have a room temperature ionic liquid ultraviolet spectrum diagram happen displacement, so in the ionic liquid and other solvent mixed solution of ultraviolet spectrum diagram, want to indicate the use of solvent. Therefore, solvent polarity and acid alkali both will have an influence on ultraviolet spectrum diagram displacement of room temperature ionic liquid.
