IMPROVED PROCESS OF PREPARATION OF LINEAR ALDEHYDES

摘要

The present invention provides an improved hydroformylation process in which the catalyst system is composed of a Group VIII metal and organic phosphite ligand having the structure P(OR)2-OR'O-P(OR)2 or P(OR)3, where R and R' are organic residues which may be the same or different and where the R or R' contain at least one C9 to C40 aliphatic group positioned as a tail extending away from the primary ligand structure rendering the ligand lipophilic.
