SYNTHESIS OF N4, N5-DI (N1’, N1'-DIDODESOXYMETHYLAZON-N'- MONODODESOXYMETHYLAZONE) DIPHENYLCARBAZONE COMPOUND AND RESEARCH AS A CORROSION INHIBITOR

On the basis of - chlordecoxymethyl ether and chlorazone, the compound N4, N5-di (N1’, N1'- didodesoxymethylazon-N'-monododesoxymethylazone) diphenylcarbazone (comp. KB-4) containing 6 groups С12Н25ОCH2, 16 nitrogen atoms, 6 groups С6Н5, 4 azonyl groups. 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.
