摘要： The present invention relates to a chemical reaction process, preferably an isomerization process, of at least one hydrocarbon in the presence of an ionic liquid. The chemical reaction is carried out in an apparatus (V1) with at least one metal halide, preferably aluminum halide, being introduced repeatedly or continuously into the apparatus (V1). The anion of the ionic liquid used comprises at least one metal component and at least one halogen component. Here, the anion of the ionic liquid and the metal halide introduced into the apparatus (V1) have the same halogen component and the same metal component. The ionic liquid used in the respective chemical reaction, in particular in an isomerization, can (inter alia) be regenerated by the process of the invention.

摘要： The present invention relates to a process for preparing cyclohexane from methylcyclopentane (MCP) and benzene. In the context of the present invention, MCP and benzene are constituents of a hydrocarbon mixture (HM1) additionally comprising dimethylpentanes (DMP), possibly cyclohexane and at least one compound (low boiler) selected from acyclic C5-C6-alkanes and cyclopentane. First of all, benzene is converted in a hydrogenation step to cyclohexane, while MCP is isomerized in the presence of a catalyst, preferably of an acidic ionic liquid, to cyclohexane. The hydrogenation is preceded by a prior removal of the dimethylpentanes (DMP), with initial removal of any cyclohexane present in the hydrocarbon mixture (HM1) together with DMP. This cyclohexane already present can be separated again from DMP in a downstream rectification step and recycled into the process for cyclohexane preparation. Between hydrogenation and isomerization, low boilers are removed and, after the isomerization, the cyclohexane is isolated with return of unisomerized MCP and optionally of low boilers.

摘要： The present invention relates to a process for preparing cyclohexane from benzene and/or methylcyclopentane (MCP) by hydrogenation or isomerization. Prior to the cyclohexane preparation, the dimethylpentanes (DMP) are removed in a distillation apparatus (D1) from a hydrocarbon mixture (HM1) comprising not only benzene and/or MCP but also DMP. If cyclohexane is already present in the hydrocarbon mixture (HM1), this cyclohexane is first removed together with DMP from benzene and/or MCP. This cyclohexane already present can be separated again from DMP in a downstream distillation step and recycled into the process for cyclohexane preparation.
