    摘要: 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.

    摘要: Provided is a process for producing alcohols or aldehydes by reacting monoolefins with carbon monoxide and hydrogen with less formation of by-products. The process comprises the step of reacting a monoolefin with carbon monoxide and hydrogen in the presence of a cobalt carbonyl catalyst until the conversion of monoolefin reaches 50-90% (the first reaction step), the step of separating unreacted monoolefin from the reaction mixture obtained in the first reaction step (the step of separation of unreacted monoolefin) and the step of reacting the separated unreacted monoolefin with carbon monoxide and hydrogen in the presence of a cobalt carbonyl catalyst (the second reaction step), wherein at least one of the first reaction step and the second reaction step is carried out in the presence of water.

    摘要: The invention relates to a process for the preparation of aldehydes in which at least one compound containing a vinyl or vinylidene group is reacted with carbon monoxide and hydrogen in the presence of a source of a metal from sub-group VIII and in the presence of a bidentate diphosphine ligand, where the diphosphine ligand has the general formula I in which A together with the phosphorus atom to which it is bonded, in each case forms a 2-phosphatricyclo[3.3.1.1{3,7}]decyl radical, in which one or more non-adjacent carbon atoms may be replaced by oxygen atoms and which is substituted or unsubstituted, and X is a bridging chain having 1 to 10 carbon atoms, and the molar ratio between the diphosphine ligand and the metal is at least 5. The process gives predominantly n-aldehydes.
