Abstract: 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 possibly 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 (that present in the hydrocarbon mixture (HM2)), while MCP is isomerized in the presence of a catalyst, preferably of an acidic ionic liquid, to cyclohexane. After the hydrogenation but prior to the isomerization the dimethylpentanes (DMP) are removed, with initial removal of the cyclohexane present in the hydrocarbon mixture (HM2) together with DMP. This cyclohexane already present prior to the isomerization can be separated again from DMP in a downstream rectification step and isolated and/or recycled into the process for cyclohexane preparation. Between the DMP removal and MCP isomerization—if low boilers are present in the hydrocarbon mixture (HM1)—low boilers are, optionally removed. After the isomerization, the cyclohexane is isolated, optionally with return of unisomerized MCP and optionally of low boilers. Preferably, cyclohexane and/or low boilers are present in the hydrocarbon mixture (HM1), and so a low boiler removal is preferably conducted between the DMP removal from isomerization. It is additionally preferable that the removal of the cyclohexane from DMP is additionally conducted, meaning that the cyclohexane component which arises in the benzene hydrogenation and may be present in the starting mixture (HM1) is isolated and hence recovered.

Abstract: Proposed is a cylindrical reactor (1) having a vertical longitudinal axis for continuous hydroformylation of a C6-C20-olefin or a mixture of C6-C20-olefins with synthesis gas in the presence of a homogeneously dissolved metal carbonyl complex catalyst, having a multiplicity of Field tubes (2) which are oriented parallel to the longitudinal axis of the reactor (1) and welded into a tube plate at the upper end of the reactor (1), having a circulation tube (3) open at both ends which envelops the Field tubes (2) and at its lower end projects beyond said tubes, having a jet nozzle (4) at the bottom of the reactor (1) for injecting the reactant mixture comprising the C6-C20-olefin, the synthesis gas and the metal carbonyl complex catalyst, wherein the Field tubes (2) are configured in terms of their number and their dimensions such that the total heat exchanger area of said tubes per unit internal volume of the reactor is in the range from 1 m2/m3 to 11 m2/m3 and the cross sectional area occupied by the Field tubes (2) per unit cross sectional area of the circulation tube (3) is in the range from 0.03 m2/m2 to 0.30 m2/m2, a gas distributor ring (5) is provided at the lower end of the circulation tube (3), at the inner wall thereof, via which a substream of the synthesis gas is feedable, and wherein one or more distributor trays (6) are provided in the circulation tube (3).

Abstract translation: 本发明涉及从甲基环戊烷（MCP）和苯制备环己烷的方法。 在本发明的上下文中，MCP和苯是另外包含二甲基戊烷（DMP），可能的环己烷和至少一种选自无环C5-C6烷烃和环戊烷的化合物（低沸点）的烃混合物（HM1）的组分。 首先，将苯在氢化步骤中转化为环己烷，而MCP在催化剂，优选酸性离子液体存在下异构化为环己烷。 之前先氢化二甲基戊烷（DMP），然后与DMP一起初始除去烃混合物（HM1）中存在的任何环己烷。 已经存在的环己烷可以在下游精馏步骤中再次从DMP分离并再循环到环己烷制备方法中。 在氢化和异构化之间，除去低锅炉，在异构化之后，环己烷被分离出来，分离出未异构化的MCP和任选的低锅炉。
