    摘要： A method for producing trans-1,4-bis(aminomethyl)cyclohexane includes a nuclear hydrogenation step of producing a hydrogenated terephthalic acid or terephthalic acid derivative by nuclear hydrogenation of a terephthalic acid or terephthalic acid derivative, the terephthalic acid or terephthalic acid derivative being at least one selected from the group consisting of terephthalic acid, terephthalic acid ester, and terephthalic acid amide; a cyanation step of treating the hydrogenated terephthalic acid or terephthalic acid derivative with ammonia, thereby producing 1,4-dicyanocyclohexane, and producing trans-1,4-dicyanocyclohexane from the obtained 1,4-dicyanocyclohexane; and an aminomethylation step of treating the trays-1,4-dicyanocyclohexane with hydrogen, thereby producing trans-1,4-bis(aminomethyl)cyclohexane.
    Metal oxide is used as a catalyst in the cyanation step, and the obtained trans-1,4-dicyanocyclohexane has a metal content of 3000 ppm or less.
