The present invention relates to a process for preparing cyclohexane by isomerizing a hydrocarbon mixture (HM) comprising methylcyclopentane (MCP) in the presence of a catalyst. The catalyst is preferably an acidic ionic liquid. The starting material used is a stream (S) which originates from a steamcracking process. The hydrocarbon mixture (HM) obtained from this stream (S) in an apparatus for aromatics removal has a reduced aromatics content compared to stream (S), and (HM) may optionally also be (virtually) free of aromatics. Depending on the type and amount of the aromatics remaining in the hydrocarbon mixture (HM), especially in the case that benzene is present, the isomerization may additionally be preceded by performance of a hydrogenation of (HM). In addition, depending on the presence of other components of (HM), further purification steps may optionally be performed prior to or after the isomerization or hydrogenation. High-purity (on-spec) cyclohexane is preferably isolated from the hydrocarbon mixture (HM) obtained in the isomerization, the specifications being, for example, those applicable to the use of the cyclohexane for the preparation, known to those skilled in the art, of caprolactam.

Process for preparing cyclohexane with starting materials originating from a steamcracking process

In a process for the cooligomerization of olefins, an olefin starting material comprising olefins having n carbon atoms and olefins having 2n carbon atoms is reacted over an olefin oligomerization catalyst to give a reaction product. The process is carried out under such conditions that the conversion of olefins having 2n carbon atoms is less than 10%. Both the cooligomer having 3n carbon atoms and the olefin having 2n carbon atoms which has been separated off from the reaction product have a high hydroformylatability.

The catalyst comprises from 0.01 to 0.5% by weight of platinum, based on the catalyst, and optionally tin, with the weight ratio of Sn:Pt being from 0 to 10, on zeolite A as support.
