Synthesis of oil-soluble corrosion inhibitors from raw materials of plant origin

Abstract

The use of low-soluble corrosion inhibitors based on raw materials of plant origin is one of the most promising methods of metalwork processing to prevent corrosion. Carbon acids with carbon radicals are used for the synthesis of such inhibitors, which participate in the formation of hydrophobic part of the molecule. It is known that the hydrophilic part of the molecule causes solubility in water, and the hydrophobic part-in hydrocarbons. The study found that by changing the structure of the hydrophilic and hydrophobic parts it is possible to obtain a substance that will dissolve in water as well as in hydrocarbons. The obtained organic compounds can be used as corrosion inhibitors, antiwear and antiadhesive additives. Therefore, by synthesizing carboxylic acids with various radicals and using them for treating metal surfaces, we can obtain not only anti-corrosion properties of the metal, but also anti-wear and anti-adhesion properties, which makes it possible to use inhibitors not only for protection against corrosion, but also for extending the service life of loaded or rubbing metal surfaces.
