    Abstract: The present invention concerns a process for preparing cyclohexane from methylcyclopentane (MCP) and benzene. In the present invention, MCP and benzene are constituents of a hydrocarbon mixture (KG1) also including dimethylpentanes (DMP), optionally cyclohexane and optionally at least one compound (low boiler) selected from non-cyclic C
    5 -C
    6 alkanes and cyclopentane. First, benzene is reacted in a hydrogenation step to give cyclohexane (present in the hydrocarbon mixture (KG2)), while MCP is isomerized to cyclohexane in the presence of a catalyst, preferably an acidic ionic liquid. After the hydrogenation but before the isomerization, the dimethylpentanes (DMP) are removed, and initially the cyclohexane present in the hydrocarbon mixture (KG2) is removed together with DMP. This pre-isomerization cyclohexane can be freed of DMP again in a downstream step of rectification and isolated and/or returned to the cyclohexane preparation process. If the hydrocarbon mixture (KG1) comprises low boilers, they can be removed between DMP removal and MCP isomerization. Following the isomerization comes the isolation of the cyclohexane, with optional recycling of unisomerized MCP and any low boilers. The hydrocarbon mixture (KG1) preferably includes cyclohexane and/or low boilers, and so low-boiler removal between DMP removal before isomerization is a preferred operation. Also preferred is an additional removal of DMP from the cyclohexane - that is, the cyclohexane fraction arising from the benzene hydrogenation and possibly forming part of the starting mixture (KG1) is isolated and hence recovered.

    Abstract: The invention relates to a method, preferably an isomerization method, for chemically converting at least one hydrocarbon in the presence of an ionic liquid and a hydrogen halide (HX). The chemical conversion is carried out in a device (V1), a gas phase being in direct contact with a liquid reaction mixture in the device (V1). The gas phase and the liquid reaction mixture each contain the hydrogen halide, and at least one hydrocarbon and the ionic liquid are additionally contained in the liquid reaction mixture. Gaseous HX is introduced into the device (V1) such that the hydrogen halide partial pressure is kept at a constant level in the gas phase. Among others, the ionic liquid used in the respective chemical conversion, in particular in an isomerization method, can be regenerated using the method according to the invention.

    Abstract: The present invention relates to a method for producing cyclohexane from benzene and/or methylcyclopentane (MCP) by hydrogenation or isomerisation. Prior to cyclohexane production, the dimethylpentanes (DMP) are separated in a distillation device (D1) from a hydrocarbon mixture (KG1) which contains DMP in addition to benzene and/or MCP. If cyclohexane is already present in the hydrocarbon mixture (KG1), the cyclohexane is separated initially with DMP in conjunction with benzene and/or MCP. The already present cyclohexane can be re-separated from DMP in a subsequent distillation step and can be recycled into the process in order to produce cyclohexane.
