To an aqueous solution (45 ml.) of potassium alum (9.17 g.) was added mono sodium salt of 3-(N-formyl-N-hydroxyamino)propylphosphonic acid (3.08 g.) with stirring, and the solution was adjusted to pH 6-7 with 10% aqueous sodium hydroxide solution and then stirred for 2 hours at ambient temperature. The precipitating materials were collected by filtration, washed twice with water (each 10 ml.) and dried to give aluminum salt of 3-(N-formyl-N-hydroxyamino)propylphosphonic acid (2.28 g.).
