摘要:
A lubricant additive having antiwear and antioxidant properties is the reaction product of a thio-dicarboxylic acid and an ether amine, preferably 3,3'-thiodipropionic acid and N-isoeicosyloxypropyl-1,3-diaminopropane which is post reacted with an aliphatic alcohol, preferably oleyl alcohol, an aliphatic amine, preferably a tert-C.sub.12 to C.sub.14 amine and/or a trialkyl phosphite, preferably a tributylphosphite. The post-reaction product contains at least one ester, amide and/or phosphonate functional group.
摘要:
The air release rate of lubricating compositions is significantly enhanced when the composition is formulated with one or more vinyl aromatic-olefin block copolymers that forms a micelle-like structure in the oil. Compositions having the specified copolymers retain less than about 2.5% air after 1 min. at 50° C. when tested by ASTM D 3427.

摘要:
Disclosed are sulfur and phosphorous free, borated organomolybdenum compositions containing borated alcohols. These compositions can be formulated with ashless antioxidants and low levels of phosphorous containing antiwear compounds to provide improved lubricating compositions.
摘要:
Polyalkylene amine coupled heterocyclic compounds are effective multifunctional additives, providing cleanliness to fuels and lubricants as well as anti-wear, friction-modifying, thermal and oxidative stabilizing properties. The beneficial effects of the product of the instant invention apparently result from an internal synergism between the polyalkylene amine groups and the heterocyclic groups.
摘要:
Organic triazole-derived carboxylic acid-esters, and ester-amide-amine salts have been found to be effective antiwear additives for lubricants and are highly useful in fuels.
摘要:
An ester-containing reaction product of a carbonyl compound, preferably an acyl halide and a thiodiphenol has high temperature antioxidant properties. The reaction product is useful as a synthetic lubricant base fluid or as an antioxidant additive when used in minor amounts of 0.01 to 10 wt. % in a mineral oil or hydrocracked oil lubricant base fluid. The reaction product can also be used in a fuel.
摘要:
Sulfur-containing ester derivatives of arylamines and hindered phenols have been found to be effective antioxidant and antiwear additives for lubricants.
摘要:
Improved grease compositions, wherein the grease is thickened with a hydroxy-carboxylate soap grease thickener, preferably a lithium 12-hydroxy stearate, and a means for increasing the dropping point which is a borated n-hydrocarbyl propylenediamine and optionally compounds containing phosphorus and/or sulfur moieties are disclosed.
摘要:
Sulfur-coupled hydrocarbyl derived mercaptobenzothiazole adducts have been found to be effective multifunctional antiwear additives for fuels and lubricants.
摘要:
N-Hydrocarbyl hydrocarbylenediamine carboxylates, which can be made by the reaction of the appropriate diamine and organic monocarboxylic acid, demonstrate friction reducing properties when formulated into lubricants, particularly lubricating oils, and fuel consumption reduction properties when formulated into such lubricants or into fuels.
