摘要:
The present invention relates to a process for the production of 1-amino-1-methyl-3(4)-aminomethylcyclohexane bya) simultaneously reacting 4(5)-aminomethyl-1-methylcyclohexene (CMA), hydrocyanic acid and aqueous sulphuric acid at temperatures of 60.degree. C. to 120.degree. C., preferably 80.degree. C. to 120.degree. C. to form 1-formamido-1-methyl-3(4)-aminomethylcyclohexane (FMA) in a first stage,b) adding water and hydrolyzing 1-formamido-1-methyl-3 (4)-aminomethylcyclohexane (FMA) and unreacted hydrocyanic acid in a second stage andc) adding a base and isolating 1-amino-1-methyl-3 (4)-aminomethylcyclohexane (AMCA) by extraction from the reaction mixture obtained in the second stage of the reaction, optionally after removing of formic acid.
