    Abstract: The invention relates to phosphacyclohexanes of general formulae I and II, wherein the following designations, among others, apply: R can represent hydrogen, C 1-100 -alkyl, C 7-20 -aralkyl, C 7-20 -alkaryl, and C 6-12 -aryl: R 1 to R 10 can independently represent hydrogen, C 1-20 -alkyl, C 7-20 -aralkyl, C 7-20 -alkaryl, and C 6-12 -aryl: W, W' can independently represent single bonds or bridges comprising 1 to 20 carbon atoms, which can form part of a cyclic or aromatic group and can be interrupted by heteroatoms. Said phosphacyclohexanes are used as ligands in transition metal complexes of transition metals belonging to groups VIII to X of the periodic table.

    Abstract: Procedimiento para la producción de aldehídos C5 y propeno a partir de una corriente de C4 conteniendo 1-buteno y 2-butenos, que contiene hasta 1000 ppm en peso de 1, 3-butadieno (corriente de C4 inicial), comprendiendo a) una etapa de hidroformilación, en la que se pone en contacto la corriente de C4 inicial con hidrógeno y monóxido de carbono en presencia de un catalizador de hidroformilación corriente y, a continuación, se separan los aldehídos C5 así formados y la corriente de C4 rica en 2-buteno así formada unos de otra y b) una etapa de metátesis, en la que se pone en contacto la corriente de C4 rica en 2-buteno formada en la etapa de hidroformilación con eteno en presencia de un catalizador de metátesis habitual y se separa el propeno de la corriente de hidrocarburos conteniendo propeno así formada.

    Abstract: A process for workin up a liquid output from a continuous hydroformylation of an olefin feedstock in the presence of a hydroformylation catalyst comprising a rhodium complex having at least one organophosphoric compound as ligand, containing unreacted olefins, alkanes, aldehyde, catalyst liquor and high-boiling by-products; which comprises stripping the liquid product phase with a stripping gas in a product phase stripper, thereby separating a vapor phase containing unreacted olefins, alkanes, aldehyde, from the catalyst residue and high-boiling by-products; recycling at least a part of the residue to the hydroformylation zone; cooling the vapor phase in a product condenser, thereby condensing unreacted olefins, alkanes, aldehyde at least partially out from the stripping gas; and recycling the stripping gas to the product phase stripper; wherein the product phase stripper and the product condenser are operated essentially isobarically.
