Abstract: The invention relates to a process for preparing 1,2-butylene oxide by the catalytic hydrogenation of vinyl oxirane on a heterogeneous catalyst by using a catalyst which contains an element from the Ist, VIIth or VIIIth subgroup of the periodic system of elements or mixtures of a plurality of these elements in the presence or absence of one or more elements acting as promoters. These elements and promoters have been applied to a metal foil or metal wire cloth support by a vapour-deposition technique.

Abstract: The invention concerns a process for preparing polytetrahydrofuran, copolymers of tetrahydrofuran and 2-butin-1,4-diol, diesters of these polymers with C2-C20 monocarboxylic acids or monoesters of these polymers with C1-C10 monocarboxylic acids by polymerizing tetrahydrofuran in the presence of one of the following telogens, water, 1,-4-butane diol, 2-butin-1,4-diol, polytetrahydrofuran with a molecular weight of between 200 and 700 Dalton, or of a C1-C10 monocarboxylic acid or a carboxylic acid anhydride produced from C2-C20 monocarboxylic acids or mixtures of these telogens on a heterogeneous carrier catalyst which contains a catalytically active amount of an oxygenous molybdenum and/or tungsten compound on an oxidic carrier material, and which has been calcined at temperatures of between 500 °C and 1000 °C after application of the precursor compounds of the oxygenous molybdenum and/or tungsten compounds to the carrier material precursors. Before it is used as a polymerization catalyst, the catalyst is activated by treatment with a reducing agent.

Abstract: A process for preparing halogen-free, reactive polyisobutene having a terminal double bond content of more than 60 mol % and an average molecular weight Mn of 800-3000 dalton by cationic polymerization in the liquid phase of isobutene over an acidic, essentially halogen-free heterogeneous catalyst, wherea) a hydrocarbon mixture of essentially C4-hydrocarbons comprising isobutene in an amount of from 10 to 80% by weight is used as the starting material andb) polymerization is carried out continuously at from -30 to 0° C. with average starting material residence times of one hour or less, where the temperature and the residence time are selected such that the isobutene conversion is less than 60% and, after separation from the resulting polyisobutene, the isobutene is either enriched in the partially converted hydrocarbon mixture and returned to the polymerization or passed to another isobutene reaction coupled with the polymerization.

Abstract: The invention provides a process for preparing polytetrahydrofuran, tetrahydrofuran copolymers, their monoesters or diesters and the monoesters or diesters of polytetrahydrofuran having a low color number in the presence of a catalyst, which comprises converting crude tetrahydrofuran which has been prepared in a manner per se into pure tetrahydrofuran by distillation, subsequently subjecting the latter to essentially complete hydrogenation and using the high-purity tetrahydrofuran obtained in this way for the polymerization directly after its preparation.
