Wood, A S; Gensheimer, D E

A chemical composition is proposed for use as a corrosion inhibitor for metals in contact with nonoxidizing acid solutions. The inhibitor can be used on such metals as iron, steel, nickel, and ferrous alloys. A synergistic, corrosion-inhibiting compound is obtained by employing as the inhibitor a mixture of 95% by volume propargyl alcohol and 5% by volume dipropargyl formal. The inhibitor mixture is used in a range from 0.001-1.0% by volume based on the volume of the aqueous acid solution in which the acid concentration ranges from 1-15%. Various acids, such as acetic, hydrochloric, phosphoric, and sulfuric are effectively protected by employing this inhibitor. (6 claims)
