Abstract: The paper discusses the relationship between the physicochemical and electronic characteristics of various metals and molecular parameters of inhibitors that allows a better prediction of the efficiency of volatile inhibitors of atmospheric corrosion (VIACs) of ferrous and nonferrous metals. The high efficiency of commercial VNKh-L inhibitors based on Schiff and Mannich bases as VIACs is substantiated. It is demonstrated by analyzing the main molecular characteristics that products of complex condensation of nitrogen-containing compounds with aldehydes can serve as highly efficient VIACs.

Keywords: physical and chemical aspects, volatile inhibitors, atmospheric corrosion, ferrous and nonferrous metals, Schiff and Mannich bases
