Abstract
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.
Claims22
A water treatment composition comprising at least one phosphonamide formed from 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 acid, and 2-phosphono-butane-1,2,4-tricarboxylic acid,
- and blends thereof to treat water.
10-35. (canceled)
A water treatment composition comprising at least one phosphonamide comprising the reaction provided between 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.
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.
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.
