VERFAHREN ZUR HERSTELLUNG VON 1,2-DIAMINO-3-METHYLCYCLOHEXAN UND/ODER 1,2-DIAMINO-4-METHYLCYCLOHEXAN
摘要:
The invention relates to a method for producing 1,2-diamino-3-methylcyclohexane and/or 1,2-diamino-4-methylcyclohexane by reacting 2,3- and/or 3,4-diaminotoluol with hydrogen under high pressure and high temperature in the presence of a heterogene catalyst containing rhodium. A mixture containing 2,3- and/or 3,4-diaminotoluol, a dialkylether and/or alicyclic ether as a solvent and ammonia is present in an autoclave in the presence of the catalyst and is subsequently hydrated by supplying hydrogen.
