The invention is a water treatment composition comprising at least one phosphonamide and blends thereof and a method to treat water. As phosphonamides are generally odorless, and typically solids, phosphonamide and phosphonamide blend compositions are generally odorless, conveniently processed and manufactured, and safely used without risks of exposure to odors and vapors associated with the corresponding amines. Advantageously, phosphonamides blended with amino-phosphate esters provide useful treatment compositions. The inventive compositions are generally used to treat water contained in water flow systems such as boilers and cooling towers.

What is claimed is: 1. A water treatment composition comprising at least one phosphonamide formed by reacting an amine selected from the group consisting of cyclohexylamine, morpholine, octadecylamine, N,N-dimethyl-1, 3-propandiamine, and ammonium hydroxide, and a phosphonic acid selected from the
What is claimed is: 1. A water treatment composition comprising at least one phosphonamide formed by reacting an amine selected from the group consisting of cyclohexylamine, morpholine, octadecylamine, N,N-dimethyl-1, 3-propandiamine, and ammonium hydroxide, and a phosphonic acid selected from the group consisting of aminotri(methylene phosphonic acid), 1-hydroxyethylidene-1,1-diphosphonic acids and 2-phosphono-butane-1,2,4-tricarboxylic acid, and blends thereof to treat water. 2. The composition of claim 1 wherein the blend comprising at least two phosphonamides formed from at least two amines and a phosphonic acid, said blend having a cumulative amine to phosphonic acid mole ratio in the range of from about 1:1 to about 10:1. 3. The composition of claim 2 wherein the phosphonamide is present in at least about 10% by weight of the composition. 4. The composition of claim 1 further comprising an amino-phosphate ester formed from a hydroxyamine and a phosphonic acid. 5. The composition of claim 4 wherein the amino-phosphate ester is present in at least about 10% by weight of the composition. 6. The composition of claim 4 wherein the hydroxyamine is selected from the group consisting of N,N-diethylethanolamine, 2-amino-2-methyl-1-propanol, 1,1-dimethylamine-propanol, and 2-dimethylamino-2-methyl-1-propanol. 7. The composition of claim 1 further comprising a hardness control agent. 8. The composition of claim 1 wherein the phosphonamide is present in at least about 10% by weight of the composition. 9. The composition of claim 1 wherein the composition is a solid. 10. A water treatment composition comprising at least one phosphonamide formed by reacting a compound selected from the group consisting of cyclohexylamine, morpholine, octadecylamine, N,N-dimethyl-1, 3-propandiamine, and ammonium hydroxide, and mixtures thereof; and a phosphonic acid selected from the group consisting of aminotri(methylene phosphonic acid), 1-hydroxyethylidene-1,1-diphosphonic acid, and 2-phosphono-butane-1,2,4-tricarboxylic acid and mixtures thereof. 11. The composition of claim 10 further comprising an amino-phosphate ester formed from a hydroxyamine and a phosphonic acid. 12. The composition of claim 11 wherein the amino-phosphate ester is present in at least about 10% by weight of the composition. 13. The composition of claim 11 wherein the hydroxyamine is selected from the group consisting of N,N-diethylethanolamine, 2-amino-2-methyl-1-propanol, 1,1-dimethylamine-propanol, and 2-dimethylamino-2-methyl-1-propanol. 14. The composition of claim 10 further comprising a hardness control agent. 15. The composition of claim 14 wherein the composition is a solid. 16. The composition of claim 14 wherein the phosphonamide is present in at least about 10% by weight of the composition. 17. The composition of claim 14 wherein the hardness control agent is a sulfonated water soluble polymeric compound. 18. A water treatment composition comprising a blend of: at least two phosphonamides, said phosphonamides formed from a reaction of a first phosphonic acid and at least two amines independently selected from the group consisting of cyclohexylamine, morpholine, octadecylamine, N,N-dimethyl-1,3-propanediamine, and ammonium hydroxide; and an amino-phosphate ester; said phosphate ester formed from a reaction of a second phosphonic acid and a hydroxyamine selected from the group consisting of N,N-diethylethanolamine, 2-amino-2-methyl-1-propanol, 1,1-dimethylamine-propanol, and 2-dimethylamino-2-methyl-1-propanol. 19. The composition of claim 18 wherein the first phosphonic acid is the same as the second phosphonic acid. 20. The composition of claim 18 wherein the first and second phosphonic acids are independently selected from the group consisting of aminotri(methylene phosphonic acid), 1-hydroxyethylidene-1,1-diphosphonic acid, and 2-phosphono-butane-1,2,4-tricarboxylic acid. 21. A composition comprising a blend of: a morpholine-1-hydroxy-ethylidene-phosphoryl-phosphonamide present in at least about 10% by weight; a cyclohexylamine-1-hydroxy-ethylidene-phosphoryl-phosphonamide present in at least about 10% by weight; and a diethylaminoethanol-1-hydroxy-ethylidene-phosphoryl-phosphonate ester present in at least about 10% by weight of the blend.
