Deactivation of rhodium hydroformylation catalysts on amine functionalized organic supports [1]

Catalyst lifetime studies have been conducted with rhodium-loaded, commercially-available amine functionalized resins for the hydroformylation/reduction of di-cyclopentadiene to dicyclopentadienedimethanol. Dowex® MWA-1 was chemically stableand no catalyst deactivation resulted; whereas, Amberlite®...

Summary:Catalyst lifetime studies have been conducted with rhodium-loaded, commercially-available amine functionalized resins for the hydroformylation/reduction of di-cyclopentadiene to dicyclopentadienedimethanol. Dowex® MWA-1 was chemically stableand no catalyst deactivation resulted; whereas, Amberlite® IRA-68 and Reilly-8050 underwent chemical reactions and catalyst deactivation resulted. The chemicaldeactivation results from a change in the tertiary nitrogen/rhodium interaction that is required for the aldehyde reduction. Consequently, as the catalyst deactivates, the aldehyde reduction is slower.
