Abstract

The present invention relates to a composition comprising:
a) at least one support material; b) at least one metal selected from transition group VIII of the Periodic Table of the Elements and c) at least one compound of the formula (I) R′-A-R″ (I), where A, R′ and R″ are each an organic radical, where R′ and R″ have the structural element —O—P(—O—) 2 with trivalent P and are bonded covalently to the A radical via the latter, with the proviso that R′≠R″, to a process for producing such a composition, to the use of the composition and to a process and an apparatus for hydroformylation in which the composition is used.

First claim

5 . The composition as claimed in claim 4 , wherein the metal is rhodium.

6 . A process for producing a composition as claimed in claim 1 , having the steps of:
A) initially charging a precursor of at least one compound of a metal from transition group VIII of the Periodic Table of the Elements; B) contacting at least one compound of a metal from transition group VIII of the Periodic Table of the Elements with a molar excess of at least one organic phosphorus compound of the formula (II)

using an inert solvent;

C) adding at least one porous inert support material to the mixture generated in B);
D) removing the inert solvent to obtain the composition.

7 . The use of a composition as claimed in claim 1 as catalyst in a process for hydroformylating unsaturated compounds.

8 . A process for hydroformylating unsaturated compounds, characterized in that a composition as claimed in claim 1 is used as catalyst.

9 . The process as claimed in claim 8 , characterized in that a fixed bed reactor containing the composition is used.
