    摘要： In a process for the hydroformylation of ethylenically unsaturated compounds, at least one complex or compound of a metal of transition group VIII with at least one bidentate phosphine ligand is used as hydroformylation catalyst and at least one of the reaction steps following the hydroformylation reaction is carried out essentially in the absence of carbon monoxide and hydrogen and in the presence of at least one monodentate phosphine ligand.

    摘要： The invention relates to a method for the continuous production of aldehydes by the isomerising hydroformylation in a homogenous phase of olefin compositions 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. The 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 the 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.

    摘要： Phosphabenzene compounds of the formulae I and II where R1 to R6 are identical or different and are, for example, hydrogen, are prepared by reacting corresponding pyrylium salts with PH3 in the presence or absence of a solvent or diluent. The pyrylium salts are combined with PH3 at above 0° C. and reacted at a temperature in the range from 0° C. to 200° C. and a pressure above 1 bar without addition of an acid catalyst or a base.
