Procedure

Reaction of amino methane diphosphonic acid with slightly more than one mole of phosphorous acid and formaldehyde yields mainly N-phosphono methylene amino methane diphosphonic acid. The reaction proceeds in a similar manner with other 1-amino alkane-1,1-diphosphonic acids such as, for instance, with 1-amino ethane-1,1-diphosphonic acid or with 1-amino propane-1,1-diphosphonic acid.
