| titleOfInvention | Inhibiting corrosion in aqueous systems |
| abstract | A process is disclosed for inhibiting corrosion of an iron based metal in contact with the system water in an aqueous system, which comprises incorporating into the system water an effective amount of bis-phosphonic acid ethers selected from the group consisting of compounds having the formula (HO)2OP-R-(OR min )n-OR-PO(OH2) wherein each R is independently selected from the group consisting of methylene and ethylene, wherein R min is selected from the group consisting of methylene, ethylene and ethylene substituted with one or more methyl groups and wherein n is an integer from 0 to 4, and water soluble salts of said bis-phosphonic acid ethers. Advantageous corrosion inhibition using the bis-phosphonic acid ethers in combination with hydroxymethylphosphonic acid is also disclosed. |
