A CALIXARENE BISPHOSPHITE LIGAND FOR USE IN HYDROFORMYLATION PROCESSES
摘要
A calixarene bisphosphite composition for use as a ligand in a transition metal-ligand complex catalyst and in a complex catalyst precursor. The ligand is especially useful in catalysts and catalyst precursors for hydroformylation processes wherein a raffinate stream comprising a mixture of alpha, beta, and iso-olefinic isomers is hydroformylated in the presence of carbon monoxide, hydrogen, and the transition metal-ligand complex catalyst to form a mixture of linear and branched aldehyde products. The complex catalyst selectively converts the alpha and beta olefin reactants more rapidly than the iso-olefin reactant resulting in an improved molar ratio of normal (linear) to branched aldehyde products. The unconverted iso-olefinic isomer is thereafter readily separated from the aldehyde product mixture.
