BIS(AMINO-METHYL)CYCLOHEXANE ISOMERIZATION METHOD

摘要

A method for isomerizing a bis(aminomethyl)cyclohexane, including an isomerization step of isomerizing the bis(aminomethyl)cyclohexane in the presence of an imine compound represented by the following general formula (1) and at least one compound selected from the group consisting of an alkali metal, an alkali metal-containing compound, an alkaline earth metal and an alkaline earth metal-containing compound:.
wherein R 1 and R 2 each independently represent a hydrogen atom or a monovalent group selected from the group consisting of a substituted or unsubstituted hydrocarbon group, a substituted or unsubstituted alkoxy group, and an acyl group (R 1 and R 2 may mutually bind to form a ring); R 3 represents a hydrogen atom or an n-valent group selected from the group consisting of substituted or unsubstituted hydrocarbon groups; and n represents an integer of 1 to 10.
