Extreme pressure agents

The base lubricant is usually a petroleum oil while the thickener usually consists of a soap or soap mixture. In addition they may contain small amounts of free alkali, free fatty acid, glycerine, anti-oxidant, extreme-pressure agent, graphite or molybdenum disulphide. [Pg.242]

Phosphorus is present in zinc dialkyldithiophosphate and deactivate platinum catalysts in engine exhaust systems. Using zinc, antimony and oxothiomolybdate dialkyl-dithiocarbamate (MoDTC) complexes alone or in combination with other lubricating oil additives appears to solve this problem. Antimony complexes are used also as extreme pressure agents while molybdenum ones as friction modifier additives (Hill et al., 1994). Analyses of Zn(dtc)2 decomposition using the thermogravimetric method, flash vacuum pyrolysis, and four-ball machine... [Pg.198]

Additives used for metal forming lubricants primarily include extreme pressure agents such as sulphurized fats and oils, sulphochlorinated fats and oils, anti-weld agents, corrosion inhibitors, buffers (alkaline reserve), biocides and chemicals used to formulate emulsions. Fatty acids or fatty compounds, as well as graphite or molybdenum disulphide, can also be used as additives. [Pg.278]
