Aluminium sulfate octadecahydrate → HCID 10992779, compound

Participants

Reaction Steps

The resultant yellow solution of sodium methyl-n-propylphosphinate is mixed with a further 1050 ml of water. 288.6 g (0.43 mol) of aluminum sulfate octadecahydrate in 300 ml of water are added dropwise at 23° C. within a period of 2 hours, with stirring, and the product precipitates immediately. The resultant solution is filtered, and the residue is washed a number of times with water. Drying under reduced pressure at 150° C. gives 330.0 g of aluminum methyl-n-propylphosphinate (99% of theory) as a white powder (m.p. >380° C.).
