The Investigation of Organic Sulfur and Phosphorus Compounds as Additives for Lubricating Oils,
Abstract
It was found that the properties of thiophosphates are influenced strongly by the size of the radical connected with the thiol sulfur. The larger the radical the higher the thermo-oxidative stability, and for O,O-dialkyl-S-alkyldithiophosphates the lower the antiwear properties of the compounds. The following compounds were shown to be promising as multifunctional antiwear additives: trialkyltetrathiophosphates, bis-(O,)-dialkylthiophosphone)disulfides, and mixed ethers of thiophosphoric acids which contain nitrogen in the alkyl radical. The introduction of a trichloromethyl group into a molecule of dialkyldithiophosphates sharply intensifies their antiwear properties. (Author)
