Abstract: A process for preparing 1,2-diamino-3-methylcyclohexane and/or 1,2-diamino-4-methylcyclohexane by reacting 2,3- and/or 3,4-diaminotoluene with hydrogen at elevated pressure and elevated temperature in the presence of a heterogeneous rhodium catalyst, wherein a mixture comprising 2,3- and/or 3,4-diaminotoluene, a dialkyl ether and/or alicyclic ether as a solvent and ammonia is initially charged in an autoclave in the presence of the catalyst and subsequently hydrogenated while supplying hydrogen.
