Abstract

The production of 2-propylheptanol described here is effected via Rh-catalyzed hydroformylation of C4-olefin to afford C5-aldehyde, aldol condensation to afford the C10-aldehyde and hydrogenation to afford the C10-alcohol. The emphasis is on the hydroformylation and the ligand employed therein. The problem addressed by the invention is that of reducing the costs of 2PH production. This problem is solved when a cheaper catalyst system which simultaneously achieves a better regioselectivity is employed in the hydroformylation. This catalyst system contains rhodium as the central atom and is complexed with the ligand (1):
