In this proceeding, the compositions of the T-30 turbine oil with oxidized liquid rubber, Ni, Co, Zn, Mg and Ba salts of the natural petroleum acids (NPA) boiling in the range 310–360⁰C and nitro compounds which are produced on the basis of C₁₄H₂₈ α-olefins have been investigated in different ratio and contents as conservative liquids. The physical and chemical properties of the produced compositions have been studied and their contents have been proved by IR spectroscopy method. It has been revealed that, the conservative liquid which is produced by the composition of the synthesized inhibitor and nitro compound in the presence of oxidized liquid rubber has a great protection against corrosion than their individual usages, meets the requirements and has a great practical importance.
