Procedure

A portion of the above pure diisobutylphosphinic acid (135.01 g, 0.758 mol) was mixed with water and neutralized with dilute aqueous sodium hydroxide solution. The neutralized product was then mixed with a solution of 61.83 g (0.256 mol) AlCl3 6H2O in 2 L water. A large amount of white precipitate was observed. The precipitate was filtered and dried to a constant weight in an oven at 105° C. A white powder, aluminum salt of diisobutylphosphinic acid, of 139.43 g was obtained. The yield was 98.9%.
