Aminoalkane polyphosphonic acids
Aminoalkanepolyphosphonic acids are a class of substances in organic chemistry . They are composed of several alkanephosphonic acid residues , all of which are bound to a central nitrogen atom.
One example is trimethylphosphonic acid amine , which can be synthesized from ammonia , formaldehyde and phosphonic acid :

Aminoalkanepolyphosphonic acids are used in detergents , especially in their sodium salt form .
