Abstract
A method for producing a thermodynamically more stable clathrate compound including at least one compound selected from the group consisting of 1,1,2,2-tetrakis(4-hydroxyphenyl)ethane, 5-hydroxyisophthalic acid, and 5-nitroisophthalic acid as a host compound and an imidazole compound as a guest compound. The method for producing a clathrate compound includes: a mixing step of mixing a mixed solvent including a protic solvent, at least one compound selected from the group consisting of 1,1,2,2-tetrakis(4-hydroxyphenyl)ethane, 5-hydroxyisophthalic acid and 5-nitroisophthalic acid, and an imidazole compound; and a heating step.
Claims6
