Inhibitors useful in preventing the corrosion of metal surfaces that contact aqueous systems containing them are disclosed. They comprise salts of polycarboxylic acids and monoamines. Typical corrosion inhibitors are made from acids such as sebacic and azelaic acid and monoamines such as ethanol amine, di- and tri-ethanol amines and N,N- diethyl-ethanol amine. |
