Procedure

Aluminum ethyl ethylphosphonate was prepared according to a known procedure: Diethyl ethylphosphonate (414 g), sodium hydroxide (199.5), and water (2.4 L) were refluxed for 4 h. A solution of aluminum sulfate hydrate (261 g) in water (830 mL) was then slowly added to form a white slurry. After filtration and drying, 319.7 g of aluminum ethyl ethylphosphonate was obtained as a white solid.
