Abstract
The problem addressed by this invention is to achieve a useful and novel method for producing dicyanocyclohexane and bis(aminomethyl)cyclohexane. This problem was solved by providing a method for producing dicyanocyclohexane having a cyanation step in which dicyanocyclohexane is obtained by a cyanation reaction of cyanocyclohexane-1-carboxylic acid and/or a salt thereof with an ammonia source, and a method for producing bis(aminomethyl)cyclohexane using the dicyanocyclohexane thus produced.
