A process for the production of 1-amino-methyl-3(4)-aminomethylcyclohexane |
| abstract |
The present invention relates to a process for the production of 1-amino-1-methyl-3(4)-aminomethylcyclohexane by a) simultaneously reacting 4(5)-aminomethyl-1-methylcyclohexene (CMA), hydrocyanic acid and aqueous sulphuric acid at temperatures of 60°C to 120°C, preferably 80°C to 120°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 and c) 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. |
