The present invention relates to a method of supplementing the catalyst in continuous hydroformylation during ongoing operation.

Method of supplementing the catalyst in continuous hydroformylation

The present invention relates to an alcohol mixture which substantively comprises alcohols having 13 or 15 carbon atoms, to a process for its preparation, to a process for functionalizing these alcohol mixtures, and to the resultant functionalized alcohol mixtures and their use.

Alcohol mixtures having 13 and 15 carbon atoms and the use thereof in the preparation of surface-active substances

The invention relates to phosphacyclohexanes of general formulae I and II, wherein the following designations, among others, apply: R can represent hydrogen, C-alkyl, C-aralkyl, C-alkaryl, and C-aryl: Rto Rcan independently represent hydrogen, C-alkyl, C-aralkyl, C-alkaryl, and C-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.

A process for selectively hydrogenating ethylenically unsaturated double bonds in polymers P involves reacting the polymers P with hydrogen in the presence of at least one hydrogenation catalyst selected from the salts and complex compounds of rhodium and/or of ruthenium in an aqueous dispersion of the polymers P that comprises not more than 20% by volume of an organic solvent. This process can be used to give hydrogenated polymer dispersions and, from these dispersions, polymers. Also claimed are aqueous polymer dispersions comprising polymers P&prime;, which include structural units I, II and III as in claim 10, with or without structural units IV and/or V as in claim 11.
