Versuchsvorschrift

800 g of the resultant mixture composed mainly of sodium diethylphosphinate were dissolved in 2500 ml of acetic acid, and 38 g (0.48 mol) of aluminum hydroxide were then added. The mixture was then heated at reflux for about 4 hours, cooled, and filtered. The resultant solid was washed first with 1 liter of glacial acetic acid, then with 1 liter of distilled water, and finally with 500 ml of acetone, and then vacuum-dried at 130° C. Yield: 183 g (92% of theory).
