Abstract
A composition and method for inhibiting corrosion by chlorine dioxide in oil field water flood systems are disclosed. The composition is comprised of an alcohol, an acid, a fatty imidazoline, an ethoxylated fatty diamine, and water. This composition has proven more effective than chromates at inhibiting the corrosion caused by chlorine dioxide, further without the serious toxicological effects caused by the use of chromates.
