| 20080251456 | Method for Separating Organic Transition Metal Complex Catalysts - Process for separating a dissolved complex catalyst of a metal of group 4, 5, 6, 7, 8, 9 or 10 of the Periodic Table of the Elements and/or any free organophosphorus ligand present from a nonaqueous hydroformylation reaction mixture which contains an aldehyde product and an organic solvent at least one membrane which is more permeable to the hydroformylation product than to the organophosphorus ligand, the separation being carried out under a carbon monoxide partial vapor pressure of more than 200 kPa. | 10-16-2008 |
| 20090163687 | PROCESS FOR PREPARING 3-METHYLBUT-1-ENE - The present invention relates to the preparation of 3-methylbut-1-ene from a hydrocarbon stream I comprising isobutene by feeding a hydrocarbon stream II which comprises at least 70% by mass of isobutene in relation to the olefins present in the hydrocarbon stream and which has been obtained from hydrocarbon stream I or is identical to it to a process step for hydroformylation in which isobutene is hydroformylated in the presence of a rhodium catalyst, hydrogenating the aldehyde obtained from the hydroformylation of isobutene to the corresponding alcohol and preparing 3-methylbut-1-ene by water elimination from the alcohol. | 06-25-2009 |
| 20090203858 | PROCESS FOR PREPARING POLYMERS FROM 3-METHYLBUT-1-ENE - The present invention relates to a copolymer which contains 3-methylbut-1-ene as a comonomer and which contains ethene or propene as a further monomer, the proportion of the incorporated 3-methylbut-1-ene being 0.1 to 40 mol %, and to a process for preparing such copolymers, the polymerization being performed in the presence of a catalyst which comprises at least one cyclopentadienyl group. | 08-13-2009 |
| 20090292146 | CATALYST PRECURSOR FOR AN Rh COMPLEX CATALYST - The present invention relates to the preparation and use of stable catalyst precursors of rhodium complex catalysts. | 11-26-2009 |
