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.

Method for producing 1,2-diamino-3-methylcyclohexane and/or 1,2-diamino-4-methylcyclohexane

Process for the continuous preparation of an amine by reaction of a primary or secondary alcohol, aldehyde and/or ketone with hydrogen and a nitrogen compound selected from the group consisting of ammonia, primary and secondary amines at a temperature in the range from 60 to 300&#xb0; C. in the presence of a copper-containing catalyst, wherein the catalytically active composition of the catalyst prior to reduction with hydrogen comprises

Method for the continuous production of an amine

Method for producing 2-alkynoic acid esters

An alkinol or mixture of two or more thereof is hydrogenated by bringing the alkinol or the mixture of two or more thereof into contact with a hydrogen-containing gas in the presence of a catalyst comprising as active metal at least one metal of transition group VIII of the Periodic Table, either alone or together with at least one metal of transition group I or VII of the Periodic Table, applied to a support, wherein the support contains macropores.
