    Abstract: Essentially monounsaturated polyalkylenes having from 30 to 700 carbon atoms are continuously hydroformylated by a process in which i) a hydroformylation-active cobalt carbonyl catalyst is prepared from a catalyst precursor dissolved in an aqueous phase in the absence of the polyalkylenes, ii) the polyalkylenes are hydroformylated by means of synthesis gas in the presence of the cobalt carbonyl catalyst in a reaction zone, iii) the cobalt carbonyl catalyst is separated from the output from the reaction zone with at least partial reformation of the catalyst precursor and the catalyst precursor is recirculated to step i).

    Abstract: The invention relates to a method for the production of aldehydes or aldehydes and alcohols by hydroformylation of olefins in the presence of a complexing catalyst homogeneously dissolved in a reaction mixture, containing a metal of Group VIIIa of the periodic table of the elements and a phosphorus-free, polydentate nitrogen compound suitable for complex formation as ligand at temperatures ranging from 50 to 100° C. and pressures from 20 to 1,000 bar and recirculating the catalyst complex in the hydroformylation reaction, wherein a) derivatized polyamines are used that are substantially non-water soluble and suitable for complex formation and have a mean molecular weight of more than 1,000 Dalton and at least 10 nitrogen atoms; b) the catalyst complex remaining in the bottom of the distillation column and the excess ligands obtained from the reaction mixture are recirculated totally or partially in the hydroformylation once the hydroformylation reaction and the separation or partial separation by distillation of the aldehydes and the alcohols has been completed; c) continues or at least batchwise evacuation of at least part of the high boiler from the bottom of the distillation of the reaction mixture is then carried out.

    Abstract: The invention relates to a method for the production of propene by multiple execution of the following sequence of steps, whereby in step 1 a mixture M1, essentially comprising unbranched C4- to C9 monoolefins (Components 04-9), 0 to 15 mol. % ethylene (component E), based on the components 04-9, 0 to 100 mol. % saturated hydrocarbons (components KG), based on the components 04-9, 0 to 30 mol. % olefins with more than 9 hydrocarbon atoms (components 0 > 9), based on components 04-9, 0 to 1 mol. %, based on the components 04-9, propene (component 03), 0 to 10 mol. %, based on the components 04-9, of other hydrocarbons (components KS), is brought into contact with a metathesis catalyst at a temperature of 20 to 350 DEG C, with the proviso that the molar proportion of the sum of the 1-olefins and the sum of the 2-olefins to the sum of the components 04-9 and 0 > 9 is at least 0.5 %, so long as the mixture M1 is not simultaneously or previously subjected to an isomerisation, correspondingly changing the proportion of 1- and 2-olefins, thus producing a mixture M2. In step II a mixture M1 is produced from a mixture M2 whereby a) propene and optionally components 0 > 9 and components KS are completely or partially removed and b) amounts of components 04-09 are added, a maximum of 1 mol. % of component E, based on the added amounts of components 04-09 and optionally other saturated or olefinically-unsaturated hydrocarbons, based on the added amounts of components 04-09, are added.

    Abstract: The invention relates to a method for the carbonylation of n-pentenoic acid or derivatives thereof of formula (I), wherein R represents CN or COOR and R represents hydrogen, alkyl or aryl. According to said method, a compound of formula (I) is reacted with carbon monoxide and a compound (II) containing a hydroxyl group in the presence of a catalyst system. The method is characterised in that the catalyst system is obtained by reacting a) a source of a metallic ion of a metal (III) of the 8 subgroup of the periodic table with b) a bidentate phosphine ligand of formula (IV), wherein R , R , R , R , R , R , R , R , R , R , R and R independently of one another represent an inorganic group, which contains a respective carbon atom, by means of which the respective group is linked to the relevant tertiary carbon atom given in formula (IV), L , L represent independently of one another a lower alkylene group and X represents an arylene group.
