Title:
METHOD FOR PRODUCING TRANS-1,4-BIS(AMINOMETHYL)CYCLOHEXANE
Document Type and Number:
WIPO Patent Application WO/2012/046782
Kind Code:
A1
Abstract:
A method for producing trans-1,4-bis(aminomethyl)cyclohexane involves: a nuclear hydrogenation step of subjecting at least one type of terephthalic acid or a derivative thereof selected from a group consisting of terephthalic acid, terephthalate esters, and terephthalic acid amides to nuclear hydrogenation to thereby obtain hydrogenated terephthalic acid or a derivative thereof; a cyanation step of bringing the hydrogenated terephthalic acid or the derivative thereof obtained in the nuclear hydrogenation step into contact with ammonia to thereby obtain trans-1,4-dicyanocyclohexane from the obtained 1,4-dicyanocyclohexane; and an aminomethylation step of bringing the trans-1,4-dicyanocyclohexane obtained in the cyanation step into contact with hydrogen to thereby obtain trans-1,4-bis(aminomethyl)cyclohexane. In the cyanation step, a metal oxide is used as a catalyst, and the metal content of the obtained trans-1,4-dicyanocyclohexane is 3000 ppm or less.
