Bondar O. Designing the inhibitors of mild steels' microbiological and acid corrosion on the basis of nitrogen-containing heterocycles.

Inhibition of microbic and acid corrosion of carbon steels new nitrogen-containing heterocycles and industrial biologically active substance are investigation object. The work purpose are studies of influence of pesticides on of soils' corrosion aggressiveness; designing and establishment of the mechanism of action inhibitors microbic and acid corrosion of a carbon steel by nitrogen-containing heterocycles: new azole derivative and industrial biologically active substances. Researches were carried out corrosion, microbiological (limiting tenfold cultivations, paper-diffusion), adsorption (measurement of a regional corner of wetting, decay curves), spectral (NMR 1Н, Auger - spectrometry), analytical (iodometric titration, chromatography), statistical methods with use of a complex of computer programs for modeling and quantum-mechanical calculations. Products of disintegration of pesticides are factors of increase of corrosion aggression of soil. Developed new inhibitors (new nitrogen-containing heterocycles with azepine cycle and industrial biologically active substances) which are effective for protection steel against microbic and acid corrosion, and as a part of compositions with vegetable origin or part of asphalt-polymer insulating mastic.
