Abstract: A process makes polytetrahydrofuran, polytetrahydrofuran copolymers, or the mono- or diesters thereof by polymerizing tetrahydrofuran and any comonomers over shaped catalyst bodies. The catalyst bodies include an acid-activated sheet silicate, where the shaped catalyst bodies have the shape of trilobes. A cross section of the trilobes is bounded by three convex curves that each make contact with a circle of diameter d that circumscribes the cross section and have three points of intersection within said circle. A distance a from any two points of intersection is 0.5 to 0.65 times the diameter d of the circle that circumscribes the cross section.

Abstract: The present invention relates to a process for preparing cyclohexane by isomerizing a hydrocarbon mixture (HM1) comprising methylcyclopentane (MCP) in the presence of a catalyst. The catalyst is preferably an acidic ionic liquid. The starting material used is a stream (S1) which originates from a steamcracking process. The hydrocarbon mixture (HM1) obtained from this stream (S1) in an apparatus for aromatics removal has a reduced aromatics content compared to stream (S1), and (HM1) may optionally also be (virtually) free of aromatics. Depending on the type and amount of the aromatics remaining in the hydrocarbon mixture (HM1), especially in the case that benzene is present, the isomerization may additionally be preceded by performance of a hydrogenation of (HM1). In addition, depending on the presence of other components of (HM1), further purification steps may optionally be performed prior to or after the isomerization or hydrogenation. High-purity (on-spec) cyclohexane is preferably isolated from the hydrocarbon mixture (HM2) obtained in the isomerization, the specifications being, for example, those applicable to the use of the cyclohexane for the preparation, known to those skilled in the art, of caprolactam.
