摘要: 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.
