  • Process for the catalytically carrying out multiphase reactions, in particular hydroformylations
    Patent number: 6492564
    Abstract: The invention relates to a catalytic process for carrying out multiphase reactions in a tubular reactor, with the catalyst being present in the continuous phase and at least one starting material in a disperse phase and the loading factor B of the tubular reactor being equal to or greater than 0.8. The process is especially suitable in particular for the hydroformylation of olefins. The aldehydes thus prepared can ideally be used for the preparation of alcohols, carboxylic acids or in aldol condensations.
    Type: Grant

  • Process for preparing higher oxo alcohols from olefin mixtures
    Patent number: 6407295
    Abstract: The invention relates to a process for preparing higher oxo alcohols from mixtures of isomeric olefins having from 5 to 24 carbon atoms by hydroformylation in the presence of a catalyst at elevated temperature and at elevated pressure, in which the hydroformylation is carried out in one stage, the olefin conversion rate for one pass is restricted to from 40 to 90% to produce a reaction mixture, and the reaction mixture is selectively hydrogenated.
