  • Patent number: 11572338
    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.
    Type: Grant

  • Patent number: 11542222
    Abstract: A method for preparing a dicyanoalkane may omit a filtration for a catalyst after a cyanation reaction can by carrying out the cyanation reaction in a state in which precipitation of a metal catalyst is suppressed. A method for preparing a dicyanoalkane may involve cyanating one or more aliphatic dicarboxylic acids and/or salt(s) thereof with an ammonia source in the presence of a predetermined compound and a catalyst, wherein, in the cyanation, the amount of the predetermined compound is maintained at a predetermined amount or more with respect to the catalyst.
