Abstract: 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.

Abstract: The present invention relates to a process for the preparation of 1-amino-1-methyl-3(4)-aminomethyl cyclohexane (AMCA) bya) catalytically hydrogenating 1-formamido-1-methyl-3(4)-cyano cyclohexane (FMC) in a first reaction stage to form 1-formamido-1-methyl-3(4)-aminomethyl cyclohexane (FMA), 1-amino-1-methyl-3(4)-formamidomethyl cyclohexane (AMF), 1-formamido-1-methyl-3(4)-formamidomethyl cyclohexane (FMF) and/or AMCA, andb) reacting FMA, AMF and/or FMF in a second reaction stage with an alkaline compound to from AMCA and a formic acid derivative, andc) separating the reaction mixture obtained in step b) into components by fractional distillation and/or by crystallization and filtration.The present invention is also relates to carrying the hydrogenation reaction of step a) in the presence of a formulating agent to form 1-formamido-1-methyl-3(4)-formamidomethyl cyclohexane (FMF).
