Abstract: Compositions containing a reverse micelle comprising a first compound and a second compound are disclosed, wherein the second compound is configured to change conformation in response to a stimulus, a first conformation selected for formation of the reverse micelle, and a second conformation selected for disruption of the reverse micelle; and wherein the first compound is selected to interact with the first conformation of the second compound to form the reverse micelle.
Abstract: Lubricating oil compositions have low friction properties and anti-wear properties and are excellent in long drain capability. The lubricating oil compositions are particularly suitable for use as a fuel efficient type lubricating oil for internal combustion engines. The lubricating oil compositions contain a lubricating oil additive comprising one or more compounds selected from a specific nitrogen-containing compound, an acid-modified derivative thereof, and an oil soluble metal complex obtained by mixing the nitrogen-containing compound and/or acid-modified derivative thereof with an organic metal salt and/or organic metal complex.
Abstract: The present invention relates to a lubricating composition containing a dispersant, a corrosion inhibitor and an antioxidant. The invention further provides a method for lubricating a mechanical device with the lubricating composition.

Abstract: Tetraaromatic diamine compounds having the general formula: are provided wherein a is 0-3; b, c and d independently are integers from 0-5, R1 and R2 together with the carbon atoms to which they are bonded are joined together to form a substituted or unsubstituted C3 to about C30 ring, saturated, partially unsaturated or fully unsaturated, optionally substituted with one or more heteroatoms, a is 0-3; b, c and d independently are integers from 0-5, R3, R4, R5 and R6 are independently hydrogen, a straight or branched C1-C30 alkyl or alkylene group optionally substituted with one or more substituents, a substituted or unsubstituted C3-C12 cycloalkyl, a substituted or unsubstituted C5-C25 aryl, a substituted or unsubstituted C6-C25 arylalkyl, a straight or branched C1-C30 alkoxy group optionally substituted with one or more substituents or two R4 substituents and/or two R5 substituents and/or two R6 substituents on adjacent carbon atoms of the aromatic ring associated therewith can be joined together to form
Abstract: Disclosed herein is a composition comprising:
(A) a lubricant, and
(B) at least one alkyl hydrazide compound of the formula:
wherein R1 is a hydrocarbon or functionalized hydrocarbon of from 1 to 30 carbon atoms, R2 and R3 are independently selected from the group consisting of hydrocarbon or functionalized hydrocarbons of from 1 to 30 carbon atoms and hydrogen.
Abstract: This invention relates to synthetic based turbo oils, preferably polyol ester-based turbo oils which exhibit exceptional load-carrying capacity by use of a synergistic combination of sulfur (S)-based and phosphorous (P)-based load additives. The S-containing additives of the present invention are thiosemicarbazide and its derivative, and the P-containing component is one or more amine phosphates. The turbo oil composition consisting of the dual P/S additives of the present invention achieves an excellent load-carrying capacity, which is better than that obtained when each additive was used alone at a treat rate higher than or comparable to the total combination additive treat rate, and the lower concentration requirement of the P-based additive allows the turbo oil composition to meet U.S. Navy MIL-L-23699 requirement on the Si seal compatibility.
