    Abstract: The present invention relates to a process for preparing a porous metal o rganic framework comprising at least two organic compounds coordinated to at least one metal ion, which comprises the steps (a) oxidation of at least on e anode containing metal corresponding to the at least one metal ion in a re action medium in the presence of at least a first organic compound, where th e first organic compound is an optionally substituted monocyclic, bicyclic o r polycyclic saturated or unsaturated hydrocarbon in which at least two ring carbons are replaced by heteroatoms selected from the group consisting of N , O and S, to form a reaction intermediate containing at least one metal ion and the first organic compound; and (b) reaction of the reaction intermedia te at a prescribed temperature with an at least second organic compound whic h coordinates to the at least one metal ion, where the second organic compou nd is derived from a dicarboxylic, tricarboxylic or tetracarboxylic acid.

    Abstract: Preparation of an ethene stream (C 2), a propene stream (C 3), an isobutene and optionally a 4C-olefin stream (C 4), a 2-methyl-2-butene and optionally 2-butene stream (C 5), and optionally other hydrocarbons containing stream (C x), optionally several separate components containing streams, comprises contacting a C4-hydrocarbon stream with ethene in a metathesis step; and separating the streams. Preparation of an ethene stream (C 2), a propene stream (C 3), an isobutene and optionally 4C olefin stream (C 4), a 2-methyl-2-butene and optionally 2-butene stream (C 5), and optionally other hydrocarbons containing stream (C x), optionally several separate components containing streams, comprises: (A) a metathesis step, in which a C4-hydrocarbon stream, containing at least 2-butene (15 wt.%), at least isobutene (5 wt.%) and 1-butene (less than 5 wt.%) (feed stream), is contacted with ethene in the presence of usual metathesis catalysts; and (B) separation of the streams (C2, C3, C4 and optionally Cx) from the obtained hydrocarbon stream, with the stream (C5) completely or partially led back to the metathesis step. Independent claims are included for methods for preparing feed stream, comprising subjecting naphtha or other hydrocarbon compounds to steam cracking or fluid catalytic cracking (FCC)-process, or dehydrating butane containing hydrocarbon stream and followed by purifying the obtained C4-olefin-mixture containing isobutene, 2-butene, butadiene, optionally butyne and optionally 1-butene, and removing the obtained stream of C4-olefin-mixture; and removing butadiene and butyne by means of selective hydrogenation to butene or butane hydride, or butadiene and butyne by extractive distillation of the obtained C4-olefin-mixture (raffinate I), where the content of 1,3-butadiene is at a maximum of 1000 wt. ppm.

    Abstract: A catalyst (I) for the gas phase hydrogenation of 4C-dicarboxylic acids and/or derivatives, preferably maleic acid anhydride, comprises copper oxide (20-94 wt.%), palladium and/or a palladium compound (0.005-5 wt.%) and an oxide support (2-79.995 wt.%) comprising oxides of Al, Si, Zn, La, Ce, Group IIIa-VIIIa elements and/or Group IA and II elements. Independent claims are also included for: (i) a process for the production of the catalyst (I) by impregnation of an oxide supported copper oxide catalyst with a solution of a soluble palladium compound, drying and optionally calcining; and (ii) a process for the gas phase hydrogenation of 4C-dicarboxylic acids and/or derivatives, preferably maleic acid anhydride in the presence of the catalyst (I).
