Reaction Steps

1-Allylimidazole (1.0 mL: 0.009 mol) was ice-cooled, and allyl iodide (2.51 mL: 0.028 mol) was added thereto dropwise. Subsequently, the temperature was gradually increased to 25° C., and subsequently stirring was carried out continuously for 24 hours. The product was a pale brown viscous liquid. This was added dropwise to 200 mL of toluene, and a viscous liquid that separated out was recovered and dried. The same procedure was repeated once more. The viscous liquid thus obtained was made into an acetonitrile solution, active carbon that had been heated and vacuum-dried was added thereto, and stirring was carried out for about 48 hours. After the acetonitrile was distilled off, the viscous liquid was recovered with dichloromethane, and the solvent was distilled off. The 1,3-diallylimidazolium iodide thus obtained was a liquid at room temperature, the amount collected was 1.81 g (yield; 71.3%), the glass transition temperature (Tg) was −68.1° C., and the ionic conductivity at 30° C. was 1.32 mS/cm. The results are given in Table 1. The structure was confirmed by 1H-NMR measurement. The results are shown below.
