Abstract:
An additive for hydrocarbon fuels comprising a demulsifier, a wax dispersant, and a napthenic oil. The additive of the present invention has been found to decrease ignition times, increase power, and reduce fuel consumption, reduce emissions, and improves cold temperature flowability.
Abstract:
Gel-free dispersant additives for lubricating and fuel oil compositions comprise at least one adduct of (A) .alpha.-olefin homopolymer or interpolymer of 700 to 10,000 number average molecular weight, free radically grafted with an average of from about 0.5 to about 5 carboxylic acid producing moieties per polymer chain, and (B) at least one non-aromatic nucleophilic post-treating reactant selected from (i) amine compounds containing only a single reactive amino group per molecule, (ii) alcohol compounds containing only a single hydroxy group per molecule, (iii) polyamine compounds containing at least two reactive amino groups per molecule, (iv) polyol compounds containing at least two reactive hydroxy groups per molecule, (v) aminoalcohol compounds containing at least one reactive amino group and at least one reactive hydroxy group per molecule, and (vi) mixtures of (i) to (v); provided that when said post-treating reactant includes one or more of (iii), (iv) or (v), the reaction between (A) and (B) is conducted in the presence of sufficient chain-stopping or end-capping co-reactant (C) to ensure that the grafted and post-reacted product mixture is gel-free.
Abstract:
The present invention is directed to an oil-soluble lubricating oil additive comprising at least one terminally unsaturated ethylene alpha-olefin polymer of 300 to 10,000 number average molecular weight substituted with mono- or dicarboxylic acid producing moieties (preferably dicarboxylic acid or anhydride moieties), wherein the terminal unsaturation comprises terminal ethenylidene unsaturation. The mono- and dicarboxylic acid or anhydride substituted polymers of this invention are useful per se as additives to lubricating oils, and can also be reacted with a nucleophilic reagent, such as amines, alcohols, amino alcohols and reactive metal compounds, to form products which are also useful lubricating oil additives, e.g., as dispersants.
Abstract:
Improved additives/detergents for lubricant and fuel compositions are obtained by condensing a hydroxyalkyl or hydroxyaryl compound with an amine compound. The condensates according to the present invention are produced by the acid catalyzed condensation of the amine reactant with the hydroxy reactant.

Abstract:
Novel phosphite derivatives of propylene based lube olefins are novel lubricating fluid media with internal synergistic multifunctional extreme pressure, antiwear and antioxidant properties. These compounds exhibit the same multifunctional characteristics when used in minor additive amounts in either mineral or synthetic lubricating oils as well as fuels.

Abstract:
Coking in and around the injector nozzles of indirect injection compression ignition engines is reduced by means of distillate fuel with which has been blended suitable concentrations of (i) organic nitrate ignition accelerator, and (ii) a dihydrocarbyl phosphite.Also described are additive mixtures of (i) and (ii) for use in distillate fuels in amounts sufficient to reduce the coking tendencies of such fuels when used in the operation of indirect injection compression ignition engines.
Abstract:
Lubricants and liquid fuel compositions containing a phosphorus oxyhalide vicinal diol reaction product provide additional protection to metal parts in contact by reducing the amount of friction.
