    摘要： A process for production, from an olefinic C4 fraction, on the one hand, of high-purity isobutene and, on the other hand, of propylene by metathesis is described. The process comprises three successive stages: 1) the selective hydrogenation of butadiene with isomerization of butene-1 into butene-2 up to thermodynamic equilibrium; 2) the separation by isobutene at the column head that integrates the hydroisomerization of n-butenes, allowing a butene-2 fraction at the bottom, and 3) the metathesis of the butene-2 fraction with ethylene. By this process, it is possible to produce in a very selective way high-purity isobutene and polymerization-quality propylene.

    摘要： In an improved process for hydroformylation of olefinically unsaturated compounds using a catalyst based on cobalt and/or rhodium employed in a two-phase medium, a catalyst based on cobalt and/or rhodium is used dissolved in a non-aqueous ionic solvent which is liquid at a temperature of less than 90° C., in which the aldehydes formed are slightly soluble or insoluble. More particularly, the catalyst comprises at least one complex of cobalt and/or rhodium co-ordinated with at least one nitrogen-containing ligand and the non-aqueous ionic solvent comprises at least one quaternary ammonium and/or phosphonium cation and at least one inorganic anion. At the end of the reaction, the organic phase is generally separated and the ionic non-aqueous solvent phase containing the catalyst can be re-used.

    摘要： A catalytic composition is obtained by mixing at least one chromium compound with at least one aryloxy compound of an element M selected from the group formed by magnesium, calcium, strontium and barium, with general formula M(RO)2-nXn, where RO is an aryloxy radical containing 6 to 80 carbon atoms, X is a halogen or a hydrocarbyl radical containing 1 to 30 carbon atoms and n is a whole number that can take values of 0 to 2, and with at least one aluminum compound selected from hydrocarbylaluminum compounds (tris(hydrocarbyl)-aluminum, chlorinated or brominated hydrocarbylaluminum compounds) and aluminoxanes. The catalytic composition can be used in an ethylene oligomerization process, in particular to produce 1-hexene.
