  • Patent number: 6835288
    Abstract: A process for preventing undesired polymerization is conducted by maintaining an effective concentration of a stabilizer which comprises N-oxyl radicals in a mixture containing ethylenically unsaturated compounds, wherein (i) an electronic signal which correlates with the concentration of the N-oxyl radicals in the mixture is obtained periodically or continuously, (ii) the electronic signal is compared with a reference value, and (iii) addition of a stabilizer to the mixture is controlled according to the comparison (ii). The signal is preferably obtained by ESR measurement. The process permits efficient use of the stabilizer.

  • Patent number: 6835855
    Abstract: In a process for the hydroformylation of ethylenically unsaturated compounds, at least one ethylenically unsaturated compound is reacted with carbon monoxide and hydrogen in the presence of a ligand-metal complex of ruthenium, rhodium, palladium, iridium and/or platinum, where the ligand-metal complex comprises a monophosphine, monophosphinite or monophosphinamidite ligand of the formula I where A together with the phosphorus atom to which it is bound forms a 2-phosphatricyclo[3.3.1.1{3,7}]decyl radical in which one or more nonadjacent carbon atoms may be replaced by heteroatoms and which may be substituted, and R′ is hydrogen or an organic radical having a molecular weight of up to 20 000 bound via a carbon atom or oxygen atom or nitrogen atom. The process is particularly useful for the hydroformylation of internal branched olefins and lower pressures and/or temperatures are required in the hydroformylation than when using other phosphorus ligands.
