PROCESS FOR THE PRODUCTION OF ACETALS FROM CARBON DIOXIDE
The invention relates to a process for the preparation of acetals from carbon dioxide. The invention also relates to a mixture of phosphorus containing ligands comprising least one polydentate ligand and at least one monodentate ligand. Further, the invention also relates to the use of mixtures comprising at least one polydentate ligand and at least one monodentate ligand in transition metal complexes for the preparation of acetals.
Catalyst composition for hydroformylation and method of preparing aldehyde using the same
The present invention relates to a catalyst composition for hydroformylation and a method of preparing an aldehyde using the same. More specifically, the present invention provides a catalyst composition for hydroformylation including a specific phosphite-based ligand and a transition metal compound in a specific amount range, thereby being capable of greatly lowering a use amount of an expensive transition metal compound and exhibiting excellent catalyst activity or stability. In addition, by using the catalyst composition in hydroformylation, excellent reaction efficiency may be provided and iso-aldehyde may be generated in high yield.
