The invention provides a process for preparing aromatic amines by catalytically hydrogenating the corresponding nitro compounds, especially for preparing tolylenediamine by hydrogenating dinitrotoluene, which comprises using hydrogenation catalysts in which the active component present is a mixture of platinum, nickel and an additional metal on a support.

Method for producing amines with a catalyst containing platinum, nickel and an additional metal

The invention relates to a shell catalyst containing ruthenium as an active metal, alone or together with at least one other metal of the auxiliary group IB, VIIB or VIII of the periodical system of the elements (CAS version), and applied to a carrier containing silicon dioxide as a carrier material. The invention also relates to a method for producing said shell catalyst, and to a method for hydrogenating an organic compound containing hydrogenable groups, preferably for hydrogenating a carbocyclic aromatic group to form the corresponding carbocyclic aliphatic groups or for hydrogenating aldehydes to form the corresponding alcohols, using the inventive shell catalyst. The invention further relates to the use of the inventive shell catalyst for hydrogenating an organic compound containing hydrogenable groups, preferably for hydrogenating a carbocyclic aromatic group to form the corresponding carbocyclic aliphatic groups or for hydrogenating aldehydes to form the corresponding alcohols.

Catalyst and process for hydrogenating organic compounds comprising hydrogenatable groups

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

A process for aminating hydrocarbons with ammonia, wherein the Ncontent in the mixture at the reactor exit is less than 0.1% by volume based on the total volume of the mixture at the reactor exit.

Direct amination of hydrocarbons

A process for aminating hydrocarbons with ammonia in the presence of catalyst (i) which catalyzes the amination, which comprises supplying oxidizing agent to the reaction mixture and reacting the oxidizing agent with hydrogen which is formed in the amination in the presence of a catalyst (ii) which catalyzes this reaction with hydrogen.
