Abstract:Rh/Biphephos is a widely used homogeneous catalyst for
the hydroformylation
of internal olefins and mixtures of olefins due to its rapid isomerization
and high n:iso selectivity. In this
work, the recycling of the catalyst via distillation in high-boiling
propylene carbonate as a catalyst phase solvent in the hydroformylation
of internal olefins was investigated. In an initial recycling experiment,
the catalyst was recycled 6 times before the Biphephos ligand was
fully decomposed via oxidation. Deactivation st… Show more
