NOVEL COMPOUND HAVING TWO-PHASE STATE AND PROCESS FOR PRODUCING THE SAME

摘要

[PROBLEMS] To provide: a compound or lithium carboxylate which has a two-phase state having a regulated crystal form and which can be used in various applications; and a process for producing the same. [MEANS FOR SOLVING PROBLEMS] A compound which has two melting points and, at a temperature between the two melting points, is in a two-phase state in which a crystalline state coexists with a liquid state; or an organic lithium oxide compound having a structure which comprises a flat ionic crystal constituted of lithium and oxygen and organic groups which each consists mainly of an alkyl chain and are chemically bonded to the crystal; or a lithium carboxylate compound which is a flat or flaky crystal and is obtained by dissolving either a combination of a carboxylic acid and lithium oxide or hydroxide or a lithium carboxylate synthesized beforehand in a mixed solvent comprising an alcohol and water and then causing precipitation. The process for lithium carboxylate compound production comprises heating either a combination of a carboxylic acid and lithium oxide or hydroxide or an existing lithium carboxylate in a mixed solvent comprising an alcohol and water to dissolve them and then gradually cooling the solution to precipitate flat or flaky crystals.
