    Abstract: A process for preparing 1-butene, which includes nonoxidatively, catalytically dehydrogenating n-butane to obtain a product gas stream of n-butane, 1-butene, 2-butene, butadiene, hydrogen, and secondary constituents; removing hydrogen and the secondary constituents to obtain a C4 product gas stream; separating the C4 product stream into a recycle stream of n-butane and a stream of 1-butene, 2-butene and butadiene by extractive distillation, and recirculating the recycle stream to the dehydrogenation zone; introducing the 1 -butene, 2-butene and butadiene stream into a selective hydrogenation zone and selective hydrogenation of butadiene to 1-butene and/or 2-butene to obtain a stream of 1-butene and 2-butene; introducing the 1-butene and 2-butene stream, and a circulating stream of 1-butene and 2-butene into a distillation zone and isolation of a product stream; and introducing the 2-butene-containing stream into an isomerization zone to obtain a circulating stream of 1-butene and 2-butene, and recirculating the circulating stream to the distillation zone.

    Abstract: PROCESS FOR CODIMERIZING OLEFINSThe present invention relates to a process for preparing olefin codimers by converting a first and second olefin starting material over a heterogeneous olefin oligomerization catalyst, to the olefin codimers obtainable by this process, to a process for preparing alcohols, in which such olefin codimers are subjected to a hydroformylation and subsequent hydrogenation, to the alcohol mixtures thus obtainable and to their use.(No suitable figures)

    Abstract: Preparation of highly reactive isobutene homo- or copolymers having Mn=from 500 to 1 000 000 by polymerizing isobutene in the liquid phase in the presence of a dissolved, dispersed or supported metal-containing catalyst complex by using, as the catalyst complex, a compound I Zn+[MXa(OR)b]n-.Lx (I) M metal atom from the group of boron, aluminum, gallium, indium and thallium, R each independently aliphatic, heterocyclic or aromatic hydrocarbon radicals which have in each case from 1 to 18 carbon atoms and may comprise fluorine atoms, or silyl groups comprising C1 to C18 hydrocarbon radicals, X halogen atoms, Z proton (n=1), optionally substituted ammonium (n=1) or n-valent metal cation, L neutral solvent molecules, a integer from 0 to 3, b integer from 1 to 4, where a+b=4, and x>=0.
