Procedure

Aluminum ethylphosphate was prepared according to a known procedure: Triethylphosphate (40 g), sodium hydroxide (17.5 g), and water (0.4 L) were refluxed for 2.5 h. A solution of aluminum sulfate hydrate (23.8 g) in water (300 mL) was then slowly added to form a white slurry. After filtration and drying, 36.7 g of aluminum ethylphosphate was obtained as a white solid.
