Reactions of Potentially Suitable Vci Compounds with Nonferrous Metals

摘要

Restrictions currently exist in the use of volatile corrosion inhibitors (VCI) because of the adverse effects on some nonferrous metals and nonmetals. Work was initiated to develop VCI's which would be inert or passive to both nonferrous metals and nonmetals but still have the ability to vaporize to to combat a corrosive environment. Possible VCI compounds were selected and their vapor pressures were measured by the Torsion-Effusion method. Vapor pressure data was obtained for amines of the nitrites, carbonates, benzoates, chromates and caprylate at 21 C. Values ranged from
