    摘要： The invention relates to a method for the continuous production of aldehydes comprising between 5 and 21 carbon atoms, by the isomerising hydroformylation in a homogenous phase of olefin compositions comprising between 4 and 20 carbon atoms and containing α-olefins and olefins with internal double bonds, by means of a synthesis gas, in the presence of a homogeneous rhodium catalyst that is complexed with an organophosphorus ligand containing oxygen atoms and/or nitrogen atoms and a free ligand. Said production is carried out at high temperature and high pressure in a multi-stage reaction system consisting of at least two reaction zones. According to said method, the olefin composition is first reacted in a first reaction zone or a group of several first reaction zones at a total pressure of between 10 and 40 bar, using a synthesis gas with a CO/H2 molar ratio of between 4:1 and 1:2 until a 40 to 95% conversion of the α-olefins is obtained. The hydroformylation product from the first reaction zone or group of several first reaction zones is then reacted in a subsequent reaction zone or group of several reaction zones at a total pressure of between 5 and 30 bar, using a synthesis gas with a CO/H2 molar ratio of between 1:4 and 1:1000. The total pressure in the subsequent reaction zone or zones is respectively 1 to (G1−Gf) bar lower than that of the preceding reaction zone, whereby G1 represents the total pressure in the respective preceding reaction zone and Gf represents the total pressure in the respective reaction zone that succeeds said first reaction zone or zones, with the proviso that the difference between G1 and Gf is greater than 1 bar and the partial CO pressure in the subsequent reaction zone or zones is respectively lower than that of the preceding reaction zone.

    摘要： A method is proposed for detecting at least one chemical compound V contained in a medium (312). The method comprises a verification step (420) which is used to determine whether V is contained in the medium (312). The method furthermore comprises an analysis step (424) in which a concentration c of the at least one chemical compound V is determined.The verification step comprises the following substeps: (a1) the medium (312) is exposed to a first analysis radiation (316) of a variable wavelength λ, the wavelength λ assuming at least two different values; (a2) at least one spectral response function A(λ) is generated with the aid of the radiation (324) absorbed and/or emitted and/or reflected and/or scattered by the medium (312) in response to the first analysis radiation (316); (a3) at least one spectral correlation function K(δλ) is formed by spectral comparison of the at least one spectral response function A(λ) with at least one pattern function R(λ+δλ), the at least one pattern function R(λ) representing a spectral measurement function of a medium (312) containing the chemical compound V and δλ being a coordinate shift; (a4) the at least one spectral correlation function K(δλ) is examined in a pattern recognition step (418), and a conclusion is made as to whether the at least one chemical compound V is contained in the medium (312); The analysis step (424) comprises the following substeps: (b1) the medium (312) is exposed to at least one second analysis radiation (318) having at least one excitation wavelength λEX; (b2) at least one spectral analysis function B(λEX,λRES) is generated with the aid of the radiation (326) of the response wavelength λRES absorbed and/or emitted and/or reflected and/or scattered by the medium (312) in response to the second analysis radiation (318) of the wavelength λEX and the concentration c is deduced therefrom.

    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.
