Summary
-
1.
Polar and protective properties have been studied for three oil fractions of Sosnino crude and for a distillate, raffinate, extract, and dewaxed oil from Zhirnovsk crude. It has been shown that the most polar products are those containing maximum amounts of medium and heavy aromatic hydrocarbons.
-
2.
The polar oil products have better protective properties, owing to the formation of adsorbed films on the metal. The protection efficiency of these films is still inadequate, so that corrosion inhibitors must be added to the oils.
