摘要:
A method of increasing the static coefficient of friction of an oleaginous composition, such as an ATF, comprising adding to a major portion of an oil of lubricating viscosity a friction increasing amount of an oil soluble friction increasing reaction product comprising (a) an oil soluble substituted or unsubstituted, saturated or unsaturated, branched hydrocarbyl group containing from about 12 to about 50 total carbon atoms, (b) a linking group, and (c) a nitrogen-containing polar group, wherein the polar group contains at least one nitrogen atom and, optionally, contains at least one atom selected from the group consisting of boron, oxygen and sulfur atoms, and wherein the polar group is linked to the branched hydrocarbyl group through the linking group.
摘要:
Friction modifier additives useful in power transmission compositions, particularly automatic transmission fluids, is disclosed. The additive comprises Component-1 alone formed by condensing a polyamine, such as tetraethylene pentamine, with an aliphatic mono acid, such as isostearic acid, or a mixture, and/or salt, of Component-1 and a Component-2 wherein Component-2 is an acid ester formed by reacting a heterodialkanol such as thiobisethanol and a hydrocarbyl substituted dicarboxylic acid or anhydride, such as octadecenyl succinic anhydride.
摘要:
This invention provides a novel antiwear and antioxidant additive for use in lubricating oils, particularly automatic transmission fluids. The novel additive is the reaction product of a phosphating agent and a thioalcohol. The reaction product is nonaggressive to silicone-based seals.

摘要:
A phosphorous- and sulfur-containing additive and its use to impart anti-wear and/or antioxidant properties to oleaginous compositions such as fuels and lubricating oils, particularly power transmission compositions, such as automatic transmittion fluids, is disclosed. The additive comprises a mixture of products formed by simultaneously reacting (1) a betahydroxy thioether, such as thiobisethanol, and (2) a phosphorous-containing reactant, such as tributyl phosphite. The reaction is carried out under reduced pressure conditions (e.g., -40 KPa to -100 KPa) to limit the amount of thioether species in said additive to less than about 45 mole %.

Lubricating oil compositions providing superior soot dispersing characteristics, which contain a combination of a high molecular weight dispersant and a soot dispersant comprising a linked aromatic oligomer
摘要:
Soot induced kinematic viscosity increase of lubricating oil compositions for diesel engines can be ameliorated by combined use of derivatized high molecular weight olefin copolymers and high molecular weight nitrogen-containing dispersant.
摘要:
A dispersant that is a reaction product of a polyalkenyl-substituted mono- or dicarboxylic acid, anhydride or ester; and a polyamine, wherein the reaction product has from greater than about 1.3 to less than about 1.7 mono- or di-carboxylic acid producing moieties per polyalkenyl moiety, and the polyalkenyl moiety has a number average molecular weight of at least about 1800, and a molecular weight distribution (Mw/Mn) of from about 1.5 to about 2.0.
摘要:
A merchandiser system and method for thawing, displaying, and warming previously baked dough products, such as cookies, under controlled drying conditions, including a warming compartment and a merchandiser. The merchandiser controls the drying of moisture in the thawed, baked products to maintain the organoleptic and/or texture properties of the products at essentially the same level as those of freshly baked products for a period of at least about 2 hours.
