| titleOfInvention | Process for the manufacture of 1-aminoalkane-1,1-diphosphonic acids |
| abstract | The invention relates to a process for making 1-aminoalkane-1,1-diphosphonic acids of the general formula (I): <IMAGE> (I) in which R stands for an aliphatic hydrocarbon radical having from 1 to 12 carbon atoms. To this end, the invention provides: (a) for tetraphosphorus hexoxide to be reacted with at least one compound of the general formula (II) <IMAGE> (II) in which R has the meaning given above and X stands for an -ONH4 or NH2-radical, in inert gas atmosphere at elevated temperature, the molar ratio of tetraphosphorus hexoxide to the compound of general formula (II) being about 1 to 2-6; and (b) for 1-aminoalkane-1,1-diphosphonic acid to be crystallized from the reaction mixture. |
