Abstract

Official abstract text for this publication.

The catalytic preparation of an aldehyde from an olefin proceeds in the presence of a monophosphite mixture.

First claim

Opening claim text (preview).

The invention claimed is: 1. A mixture, which comprises a mixture of compounds 1 and 2: 2. A complex mixture, comprising: are according to claim 1 , and a metal atom selected from the group consisting of Rh, Ru, Co, and Ir. 3. The complex mixture according to claim 2 , wherein said metal atom is Rh. 4. A process for hydroformylation of an olefin, comprising: a) initially charging an olefin, b) adding a mixture according to claim 1 c) adding a compound comprising one of the following metals: Rh, Ru, Co, or Ir, to obtain a reaction mixture, c) feeding H 2 and CO into the reaction mixture, d) heating the reaction mixture, to convert the olefin to an aldehyde, wherein the additions in process steps b) and c) can also be effected in one step through the addition of a corresponding complex mixture. 5. The process according to claim 4 , wherein the olefin is a mono-olefin having 2 to 24 carbon atoms, and having a terminal or an internal C≡C double bond. 6. The process according to claim 4 , wherein the olefin is an α-olefin, terminally branched, internal and internally branched olefin. 7. The process according to claim 4 , wherein a terminally hydroformylated olefin is obtained.
