306 g (1 mol) of hexadecylphosphonic acid (produced as in example 13) are suspended in 1.5 l of hexane and 200 ml of a 10 molar solution of sodium hydroxide are added; the suspension is refluxed for 2 hours and water removed by azeotropic distillation. The reaction solution is filtered and the residue is washed with water and hexane and dried under reduced pressure to obtain 340 g (97% of theory) of hexadecylphosphonic acid disodium salt as a colorless solid.
