A crude liquid containing 1,3-bis(aminomethyl)cyclohexane and a high-boiling component having a boiling point higher than that of 1,3-bis(aminomethyl)cyclohexane is distilled. By controlling the distillation conditions, the high-boiling component is prevented from entering into a distilled 1,3-bis(aminomethyl)cyclohexane and the content of a low-boiling component in the distilled 1,3-bis(aminomethyl)cyclohexane is minimized.
通过蒸馏含有1,3-双(氨甲基)环己烷和沸点高于1,3-双(氨甲基)环己烷的高沸点组分的原始液体。通过控制蒸馏条件,防止高沸点组分进入蒸馏的1,3-双(氨甲基)环己烷中,并使蒸馏的1,3-双(氨甲基)环己烷中低沸点组分的含量最小化。
