摘要:
A method for producing bis(aminomethyl)cyclohexanes includes a nuclear hydrogenation step of producing hydrogenated phthalic acids or phthalic acid derivatives by nuclear hydrogenation of phthalic acids or phthalic acid derivatives of at least one selected from the group consisting of phthalic acids, phthalic acid esters, and phthalic acid amides; a cyanation step of treating the hydrogenated phthalic acids or phthalic acid derivatives obtained in the nuclear hydrogenation step with ammonia, thereby producing dicyanocyclohexanes; and an aminomethylation step of treating the dicyanocyclohexanes obtained in the cyanation step with hydrogen, thereby producing bis(aminomethyl)cyclohexanes. In the cyanation step, metal oxide is used as a catalyst, and the obtained dicyanocyclohexanes have a metal content of 3000 ppm or less.
