Abstract: PCT No. PCT/EP95/00825 Sec. 371 Date Sep. 13, 1996 Sec. 102(e) Date Sep. 13, 1996 PCT Filed Mar. 6, 1995 PCT Pub. No. WO95/25080 PCT Pub. Date Sep. 21, 1995An industrial preparation of aldehydes and/or alcohols from olefins of more than 3 carbon atoms by a catalytic hydroformylation of the olefin reactant at a pressure of from 50 to 1000 bar and a temperature of from 50 to 180 DEG C. in the presence of an uncomplexed rhodium catalyst homogeneously dissolved in the reaction medium. The catalytic activity of the rhodium is maintained, first by extracting it from the initially discharged reaction mixture by means of an aqueous solution of a nitrogen-containing complexing agent such as sulfonated or carboxylated pyridines, quinolines or the like. In a recycle of the complexed rhodium to be reused in the hydroformylation reaction, the aqueous rhodium-containing extract is fed to a precarbonylation stage where it subjected to a required precarbonylation in the presence of an essentially water-insoluble organic liquid and in the presence of carbon monoxide, synthesis gas or another gas mixture containing carbon monoxide at from 50 to 1000 bar and from 50 to 180 DEG C. The mixture discharged from this precarbonylation stage is then separated into an organic phase containing the main part of the rhodium and an aqueous phase containing the complexing agent. The resulting rhodium-containing organic phase with the regenerated catalyst is then fed into the hydroformylation stage to complete its recycle.

Abstract: The invention concerns a process for preparing 6-aminocapronitrile or 6aminocapronitrile-hexamethylene diamine mixtures by: a) reacting 5formylvaleronitrile with ammonia and hydrogen in the presence of hydrogenation catalysts selected from the group comprising metals or metal compounds of rhenium, copper and elements of the eight subgroups, a hydrogenation discharge product being obtained; and b) extracting from the hydrogenation discharge product 6-aminocapronitrile and optionally hexamethylene diamine, provided that the hydrogenation catalyst does not contain copper, nickel or copper and nickel as its only components.
