Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for producing a thermodynamically stable crystal of a clathrate compound, comprising a mixing step of mixing the following component (A), component (B), and component (C); and a heating step: (A): a mixed solvent comprising a first solvent which is at least one solvent selected from the group consisting of water and methanol; and a second solvent which is at least one solvent selected from the group consisting of ethyl acetate, hexane, methyl ethyl ketone, and methanol, the second solvent being a solvent different from the first solvent, (B): at least one compound selected from the group consisting of 1,1,2,2-tetrakis(4-hydroxyphenyl)ethane and 5-hydroxyisophthalic acid, (C): at least one compound selected from the group consisting of 2-phenyl-4-methyl-5-hydroxymethylimidazole and 2-ethyl-4-methylimidazole. 2. A method for producing a thermodynamically stable crystal of a clathrate compound which is different from (D) by crystal transformation comprising a mixing step of mixing the following component (A) and component (D); and a heating step: (A): a mixed solvent comprising a first solvent which is at least one solvent selected from the group consisting of water and methanol; and a second solvent which is at least one solvent selected from the group consisting of ethyl acetate, hexane, methyl ethyl ketone, and methanol, the second solvent being a solvent different from the first solvent, (D): a clathrate compound comprising at least one compound selected from the group consisting of 1,1,2,2-tetrakis(4-hydroxyphenyl)ethane, and 5-hydroxyisophthalic acid and at least one compound selected from the group consisting of 2-phenyl-4-methyl-5-hydroxymethylimidazole and 2-ethyl-4-methylimidazole.
