Method for determining suitability of triorganophosphorus ligands for use in hydroformylation processes

摘要

The purity, and thus suitability of triorganophosphorus ligands of the same chemical composition obtained from different sources for use in forming catalytic complexes for catalyzing hydroformylation reactions is determined by heating an admixture of the organophosphorus ligand and an aldehyde, measuring the amount of resultant condensation products, and comparing said amount to a standard.
