Abstract
The synthesis of amide complexes of O,O-di(alkyl)aryldithio phosphates of metals (Co, Cu, Zn) with acetamide, benzamide and salicylamide was carried out. It was found that one of the advantages of these amido complexes is the absence of odour amines and the possibility of their use in neutral, acidic and hydrocarbon media. The composition and structure of the obtained amido complexes were confirmed by analytical procedures and IR spectroscopy. The anticorrosion properties of preservation liquids based on the synthesized amido complexes with the spent turbine oil T-30 were studied on steel plates in three media: in a G-4 hydrochamber (temperature 40±2 °C, humidity 95±3 %); in seawater; in the 0.001 % solution of sulphuric acid. Their high efficiency against corrosion was revealed.
