| Zusammenfassung: | The present invention is a method for producing optically active trans-1,2-diaminocyclohexane by crystallizing optically active trans-1,2-diaminocyclohexane from a solution of optically active trans-1,2-diaminocyclohexane to thereby produce crystals of optically active trans-1,2-diaminocyclohexane. According to the present invention, it becomes possible to produce high-purity optically active trans-1,2-diaminocyclohexane from a solution of optically active trans-1,2-diaminocyclohexane with high yield. High-purity optically active trans-1,2-diaminocyclohexane produced by the method for producing optically active trans-1,2-diaminocyclohexane according to the present invention is useful as a raw material for many medicines. |
