    摘要： The present invention provides a process for changing the given mean molecular weight Mn in the continuous preparation of polytetrahydrofuran or tetrahydrofuran copolymers, the mono- or diesters of polytetrahydrofuran or of tetrahydrofuran copolymers by polymerizing tetrahydrofuran in the presence of a telogen and/or of a comonomer over an acidic catalyst, wherein a) the molar ratio of telogen to tetrahydrofuran or to tetrahydrofuran and comonomer is changed, b) then the mean molecular weight of at least one sample is determined, c) until the mean molecular weight thus determined differs from the molecular weight to be achieved by the change, the already formed polytetrahydrofuran or the tetrahydrofuran copolymers, the mono- or diesters of polytetrahydrofuran or tetrahydrofuran copolymer is at least partly depolymerized over an acidic catalyst and d) the tetrahydrofuran recovered by depolymerization is recycled at least partly into the polymerization.

    摘要： The present invention relates to a process for improving the catalytic properties of a catalyst comprising one or more elements selected from the group consisting of cobalt, nickel and copper, said catalyst being present in the form of a structured monolith, by contacting the catalyst with one or more basic compounds selected from the group of the alkali metals, alkaline earth metals and rare earth metals. The invention further relates to a process for hydrogenating compounds which comprise at least one unsaturated carbon-carbon, carbon-nitrogen or carbon-oxygen bond in the presence of a catalyst comprising one or more elements selected from the group consisting of cobalt, nickel and copper, said catalyst being present in the form of a structured monolith, by contacting the catalyst with one or more basic compounds selected from the group of the alkali metals, alkaline earth metals and rare earth metals. The present invention also relates to the use of a basic compound selected from the group of the alkali metals, alkaline earth metals and rare earth metals for improving the catalytic properties of a catalyst comprising cobalt and/or copper and/or nickel, said catalyst being present in the form of a structured monolith.
