Abstract
Dicyclohexylammonium nitrite is a powerful inhibitor for corrosion of steel by fresh water. Since this nitrite salt is slightly volatile, it has commercial application in a new method for preventing corrosion of packaged steel articles by the moisture that enters or is present within a package. It functions by vaporization and transport of its vapor to the metal surface where it condenses or dissolves in condensing moisture. The duration of protection is dependent upon the quantity of inhibitor present and the rate of loss as vapor and by decomposition. The compound has properties of chemical stability, compatibility, volatility, vapor transport, diffusion, solubility, and corrosion inhibition, that are important to its functions as an inhibitor in packages. The absence of undesirable effects with nonmetallic materials, nonferrous metals, bi-metallic couples and in handling by people are also of practical importance. A large number and variety of tests in the laboratory and in outdoor exposure racks have ...
