摘要：The invention relates to a method for producing cyclohexane by isomerizing ahydrocarbon mixture (KG1) containing methylcyclopentane (MCP) in the presence of acatalyst. The catalyst is preferably an acidic ionic liquid. A flow (S1) originating from asteam cracking process is used as a starting material. The hydrocarbon mixture (KG1) is

obtained from said stream (S1) in a device for removing aromatics. The hydrocarbonmixture has a reduced aromatic content in comparison with the flow (S1). (KG1) can alsobe (nearly) free of aromatics. In dependence on the type and amount of the aromaticsremaining in the hydrocarbon mixture (KG1), in particular if benzene is present, ahydrogenation of (KG1) additionally can be performed before the isomerization.Furthermore, additional purification steps can optionally be performed before or afterthe isomerization or hydrogenation in dependence on the presence of other componentsof (KG1). Preferably high-purity cyclohexane (in accordance with specifications) is isolatedfrom the hydrocarbon mixture (KG2) arising during the isomerization, wherein thespecifications are given, for example, by the use of the cyclohexane for the production ofcaprolactam known to the person skilled in the art.
