Corrosion inhibitor mixture
In the use of aqueous acidic baths to treat metals, additives or inhibitor in the baths are desirable to prevent or inhibit corrosion or erosion of the metal surfaces. Similarly, in the field of oil-well acidizing, it is necessary to use inhibitors in order to prevent corrosion of the oil-well equipment by the aqueous acid solutions employed. Various other industrial operations also involve contact between an aqueous acidic solution and a metal, and an inhibitor must be used in order to minimize corrosion and/or consumption of the metal by such contact. Aqueous acid solutions are inhibited against corrosion of metals, especially ferrous metals, by incorporation of a corrosion- inhibiting mixture composed of a combination of 1-hexyn-3- ol, 5-decyn-4, 7-diol and urea.
