ABSTRACT:
Arylphosphinic acids are prepared by reacting an aromatic compound with phosphorus trichloride in the presence of aluminum chloride to form an aluminum/phosphorus complex and then hydrolyzing the complex with aqueous phosphoric acid to form the arylphosphinic acid as an insoluble phase and a soluble aluminum salt. The arylphosphinic acid and aluminum salt are then easily separated.
