Although the discovery of aluminum dates back little more than a century, its use as a structural material has gained precedence over most metallic elements know to man from earliest history. Emerging from a few shiny globules displayed as curiosities into practically all fields in so short a period of time, indicates its possession of exceedingly superior characteristics, both physical and chemical. Paramount among these is perhaps its stability toward many corrosive influences. No element or metal possesses unlimited qualifications under all conditions of environmental stress and aluminum is no exception. Although it shows superior resistance in many respects especially in acid media, it breaks down in the presence of solutions of an alkaline nature. Recent investigations show that small amounts of certain heterocyclic compounds containing nitrogen prove satisfactory in minimizing the attack of electrolytes on the various forms of iron. This increase is attributed to a passivating effect of the metal by the addition compounds. The present investigation is made on aluminum to ascertain the inhibiting effect of various series of organic compounds in the presence of an attacking medium.
