Abstract

The present invention relates to a catalyst composition that includes a triphenylphosphine ligand, a monodentate phosphine ligand, a monodentate phosphine oxide ligand, and a transition metal catalyst, and a hydroformylation process using the same. In the hydroformylation process using the catalyst composition according to the present invention, the high catalytic activity can be obtained, and the selectivity (N / I selectivity) in respects to normal- or iso-aldehyde can be desirably controlled.

Description

technical field [0001] The present invention relates to a phosphorus-containing catalyst composition and a hydroformylation method using the phosphorus-containing catalyst composition, more specifically, the present invention relates to A catalyst composition of a compound and a transition metal catalyst, and a hydroformylation process using the catalyst composition. Background technique [0002] In 1938, Otto Roelen in Germany initially discovered the hydroformylation reaction, in which olefins and synthesis gas (CO / H 2 ) are reacted in the presence of a homogeneous organometallic catalyst and a ligand to produce linear (n-) and branched (iso-) aldehydes with one more carbon atom than the alkene. [0003] In general, hydroformylation as a carbon-based synthesis reaction is a very important industrial reaction in view of homogeneous system catalyzed reactions, and currently, aldehydes (including alcohol derivatives) About 9,600,000 tons (SRI report, September 2006, 682.700...
