| Popis: | 1. Laboratory tests have been conducted of metal (Ba, Ca, Zn, Pb, Ni) dialkyl and diaryldithiophosphates and also of zinc dialkylmonothiophosphate and phosphate as antioxidants and corrosion inhibitors at various temperatures. It is shown that all the compounds tested, except for zinc di(2-ethylhexyl) phosphate, retard the oxidation of hydrocarbons and are corrosion inhibitors. With an increase in temperature the action of the majority of additives is weakened. 2. Zinc and barium dinonylphenyldithiophosphates exhibit the greatest antioxidant and anticorrosion properties at ail temperatures tested. 3. It has been established that the anticorrosion activity, and the antioxidant activity of additives of the metal dialkyldithiophosphate type is caused primarily by the presence of thioic sulfur. |
