    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 and a hydrogen halide (HX). The chemical reaction is carried out in an apparatus (V1) in which a gas phase is in direct contact with a liquid reaction mixture. The gas phase and the liquid reaction mixture each comprise the hydrogen halide and the liquid reaction mixture additionally comprises at least one hydrocarbon and the ionic liquid. Gaseous HX is introduced into the apparatus (V1) in such a way that the hydrogen halide partial pressure is kept constant in the gas phase. 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 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 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.
