FIELD: metallurgy. ^ SUBSTANCE: invention concerns chemical safeguarding methods of hydrocarbons. Particularly it concerns absorbents of oil- absorptive plants, from oxidation and decomposition, and also protection of internal surfaces of process equipment and pipelines of defined plants against corrosive attack and formation of sludgy deposits. In the capacity of oxidation inhibitor of hydrocarbons, ferrous metal corrosion and formation of sludgy deposits there are used derivatives of Mannich basis of general formula: , where R - CH3, alkyl or alkylen with carbon atoms quantity C3-C20, R1 - alkyl with carbon atoms quantity C4-C12, alkyl aryl C8H9, R2 - H, alkyl aryl C8H9, n - 1, 2, 3. Inhibitor provides oxidation processes braking in absorbent, high-repeatability protection against corrosive attack of metallic equipment, effective flushing from inner surfaces of process equipment of sludgy deposits, and also prevents repeated deposit formation. ^ EFFECT: providing of oxidation processes braking in absorbent, high-repeatability protection against corrosive attack of metallic equipment, effective flushing from inner surfaces of process equipment of sludgy deposits, and also prevents repeated deposit formation. ^ 2 tbl, 7 ex |
