During the study, it was found that these new compounds have both economic and environmental highperformance inhibitory properties. Under laboratory conditions, the anti-corrosion inhibitory effectiveness of the KB-4 compound was determined. In the study of 0.20; 0.25; 0.5 mg/l concentrations of compound KB-4, its inhibitory efficiency was 99.96-100%. From an environmental and economic point of view, this compound is several times more effective than the inhibitors currently used in the oil and gas and petrochemical industries to protect steel process equipment in the most aggressive environments. Thus, the use of a new guanidine derivative compound KB-4 for corrosion protection of steel process equipment in the oil and gas and petrochemical industries can be considered scientifically substantiated.

The improvement of the quality of road oil bitumen, including the thermooxidative resistance to aging, at the production stage with the reduction of the oxidation temperature has been theoretically and empirically justified. BND 60/90 bitumen samples were taken during the research. The samples taken were analyzed according to the temperatures of 200, 220, 250 and 280 ℃. Here, in order to increase the resistance of bitumen samples taken at 160 ℃ to aging due to thermooxidative effect, softening temperature, fragility temperature, penetration at 25 ℃, mass loss, limiting shear stress, softening temperature in Petri cups and the relationships between them were studied in different regimes. It was determined that the preparation of asphalt-concrete mixtures and road surfaces from bitumen obtained as a result of oxidation of raw materials at a temperature of 220 °C is considered more favorable. It has been studied that bitumen oxidized at a temperature of 220 ℃ allows to extend the service life by 1.3-1.5 times due to its aging resistance.
