Procedure

Phenyl phosphonic acid (40.0 g, 0.25 mol) was taken in a 200 mL round-bottom flask, a 60% of fuming sulfuric acid (77.3 g, 0.58 mol) was added and stirred under heating at 80° C. for one day under a nitrogen gas stream. Then, after cooling the reaction mixture in an iced bath, water (86.0 g) was added to form a 12N sulfuric acid solution (32 wt %) of 3-sulfophenyl phosphonic acid. This stock solution was portioned into a predetermined small amount and used for the synthesis of the zirconium phosphonate copolymer.
