Abstract: A sulfonate-based grease composition and method of manufacture comprising the addition of one or more glycerol derivatives. The glycerol derivative acts to optimally disperse the thickener in the grease such that the conventional step of milling the grease may not be needed. The glycerol derivative reacts with water to form in-situ complexing acids, which may replace at least some of the normally used complexing acids for reacting with calcium containing bases. The greases according to preferred embodiments have a high dropping point, improved thickener yield, and faster conversion time.

Abstract: A lubricating oil composition comprising a zinc dithiocarbamate fraction, for use in a gasoline or diesel engine equipped with fluoroelastomer seals, wherein said zinc dithiocarbamate fraction consists essentially of zinc dithiocarbamate molecules per Formula I: having alkyl groups R1, R2, R3, and R4, wherein the weighted total average for carbon chain lengths for all molecules together is 9 or more:

Abstract: A novel molybdenum dithiocarbamate composition is produced by preparing a di-tridecylamine (DTDA) intermediate from a butylene feedstock comprising greater than 50% 2-butylene, and preparing a molybdenum dithiocarbamate composition from the DTDA intermediate.

Abstract: An extreme pressure additive composition for use in grease contains alkaline earth metal derivatives of 2,5-dimercapto-1,3,4-thiadiazole (DMTD) complexed to alkylene glycol fluids and or PAG fluids. In addition, additives for extreme pressure and antiwear contain a complex of alkali and/or alkaline earth metal derivatives of DMTD with alkylene glycol fluids and or PAG fluids, in combination with an organophosphorus compound.

Abstract: Compositions comprising silicone fluids are formulated to provide improved metal-to-metal lubrication. Such Lubricating compositions comprise a major amount of (1) one or more siloxane polymer (“silicone fluids”) selected from dimethyl siloxane polymers (also known as dimethyl silicone) and/or phenylmethyl dimethyl siloxane copolymers (also known as phenyl silicone), and lesser amounts of (2) synthetic and/or bio-based ester co-fluid, and (3) an alkoxylated aliphatic polyamine derivative. Unexpectedly, the compositions show a significant improvement in metal-to-metal lubrication, performing better than either the silicone fluids alone or and a combination of silicone with-ester and or silicone with-alkoxylated aliphatic polyamine combinations.

Abstract: Antimony dithiocarbamate is known to provide extreme pressure (EP) protection in lubricating compositions, such as grease. However, there is a desire to reduce the amount of antimony used in such compositions, while still maintaining acceptable EP performance. It has now been found by using small amounts of either ammonium dithiocarbamate or zinc dithiocarbamate in combination with the antimony dithiocarbamate (SbDTC), a lower amount of SbDTC can be used in the lubricating composition while still maintaining excellent or exceptional EP protection. To counteract the corrosive effects of the SbDTC and ammonium dithiocarbamate composition, it has been found that compounds containing a carboxylic acid group are effective in avoiding copper corrosion.
