Title:
イミダゾリウム系溶融塩型電解質の調製方法
Document Type and Number:
Japanese Patent JP4092517
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To synthesize a compound made by introducing various kinds of anions into an imidazolium salt and thereby provide a stable electrolyte in relation to temperature by including, in it as an effective ingredient, an N- alkylimidazolium salt provided by reacting an N-vinylimidazole compound having a vinyl group only in either the first position or the third position with acid. SOLUTION: It is preferable that an N-vinylimidazole compound having a vinyl group only in either the first position or the third position is reacted with acid, and an N-vinylimidazolium salt provided by polymerizing the resultant reaction product is used as an effective ingredient. This electrolyte is provided by performing the neutralization reaction of the N-vinylimidazole compound with an inorganic acid such as a hydrobromic acid, hydrochloric acid, nitric acid, fluoroboric acid, or an organic acid such as an acetic acid. In order to react the N-vinylimidazole compound with an acid, for instance, they are stirred and mixed in an aqueous solution at 0-20 deg.C, excessive water is collected and removed from the reaction solution, and the electrolyte is extracted by using an organic solvent such as diethyl ether.
