The present invention relates to a process for preparing hydroformylation products of olefins having at least four carbon atoms, in which a high proportion of both the linear C-olefins having a terminal double bond comprised in the olefin-comprising feed used and of the linear C-olefins having an internal double bond is converted into hydroformylation products. Furthermore, the invention relates to a process for preparing 2-propylheptanol which comprises such a hydroformylation process.

Method for the hydroformylation of olefins

The present invention relates to a process for the hydroformylation of ethylenically unsaturated compounds by reaction with carbon monoxide and hydrogen in the presence of a catalytically active fluid which comprises a dissolved metal complex of a metal of transition group VIII of the Periodic Table of the Elements with at least one phosphoramidite compound as ligand, wherein the fluid is brought into contact with a base.

Stabilization of hydroformylation catalysts based on phosphoramide ligands

Process for preparing aminodihalophosphines, diaminohalophosphines, triaminophosphines, phosphorous ester diamides, aminophosphines, diaminophosphines, phosphorous ester amide halides and aminophosphine halides with elimination of an acid in the presence of an auxiliary base, wherein the auxiliary base

Method for the separation of acids from chemical reaction mixtures by means of ionic fluids

The present invention relates to a process for asymmetric synthesis in the presence of a chiral catalyst comprising at least one complex of a metal of transition group VIII with ligands capable of dimerization via noncovalent bonds, such catalysts and their use.

Method for asymmetric synthesis

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/Hmolar ratio of between 4:1 and 1:2 until a 40 to 95% conversion of the &#x3b1;-olefins is obtained.

Method for the continuous production of aldehydes

The invention relates to a method for producing dialdehydes and/or ethylenically unsaturated monoaldehydes by reacting at least one compound with at least two ethylenically unsaturated double bonds with carbon monoxide and hydrogen in the presence of a hydroformylating catalyst with at least one complex of a metal of subgroup VIII. The subgroup comprises at least pnicogen chelate ligands.

Method for producing dialdehydes and or ethylenically unsaturated monoaldehydes by hydroformylating ethylenically unsaturated compounds

The present invention relates to a process for hydroformylating in the presence of a catalyst comprising at least one complex of a metal of transition group VIII with mono-phosphorus compounds which are capable of dimerizing via noncovalent bonds as ligands, to such catalysts and to their use.
