The anticorrosive action on Pb of alkylphenolic, sulfonated, and antioxidant additives used in various concentrations in Baku and Eastern U.S.S. R. oils was studied during oxidation of the oils at 150C for 25 hrs. The corrosion decreased with an increase of alkylphenol additive concentration. The sulfonated oil additive, SB-3 Ba salt of sulfonic acids of sulfurized diesel oil, had an anticorrosive action for 15 hrs. but, after 20-25 hrs., the corrosion was 10-12 higher than that in an oil without additive. The antioxidant additive, DF-11 Zn dialkyl dithiophosphate and the antiwear additive LZ-23K ethylene diisopropylxanthate in small amounts 0.5-1.2 strongly decreased the corrosion.
