Ionic liquids combine a set of proper ties like non-flammability, non-volatility, high ionic density and intrinsically high ionic conductivity; they also behave as good solvents for various chemical and electrochemical processes. These attributes make them appealing as alternative materials to replace conventional solvents, wherefore the interest in ionic liquid based materials for diverse electrochemical devices has boosted in the last few decades. The halogenated hydrocarbon and pyridine are used in the preparation of room temperature ionic liquid intermediates bromided N-octyl pyridine OPB, and the intermediate infrared spectrometer are used in chemical structure characterization, so it is determined that the product is the room temperature ionic intermediates OPB. Infrared spectrometer for the structure characterization is used, it is proved that OP-BF4 room temperature ionic liquid has been gotten. Both solvent polarity and acid alkali have an influence on ultraviolet spectrum diagram displacement of room temperature ionic liquid. If the ultraviolet spectrum diagram of ionic liquids and other solvent mixed solution is studied, it is necessary to indicate which solvent is used.
