ACID-BASE MIXTURE AND ION CONDUCTOR COMPOSED OF SUCH MIXTURE

Disclosed is an acid-base mixture composed of a base component and an acid component, wherein at least one of the base component and the acid component contains at least two compounds, and the base component contains at least one compound of formula (1): wherein R 1 , R 2 , and R 3 each represent a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms, provided that at least one of them is a hydrocarbon group. Also disclosed is an ion conductor comprising an acid-base mixture composed of an acid component and a base component including at least one compound of formula (2): wherein R 1 , R 2 , and R 3 each represent a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms, provided that R 1 and R 3 are different.
