Anticorrosion Properties of the Extract of Rapeseed Oil Cake as a Volatile Inhibitor of the Atmospheric Corrosion of Steel

  • Published:
Materials Science Aims and scope

We study the composition of the volatile fractions of the isopropanol extract of rapeseed (Brassicaceae family) oil cake by the chromatography-and-mass spectrometry method. It is shown that their main ingredients are glycosides, ketones, aldehydes, saturated and unsaturated fat acids, and steroids. It was discovered that the extract provides a high level of corrosion protection of the metal as a volatile corrosion inhibitor under the conditions of periodic condensation of moisture. It is demonstrated that the corrosion rate of steel decreases as its concentration increases, and the process of formation of films from the vapor phase has a long-term character. The film formed on the surface of steel from the gas–vapor phase of the extract gives an aftereffect on a level of 90% under the conditions of periodic moisture condensation for 504 h.
