Abstract:
A fuel composition comprising a major amount of hydrocarbon fuel and a minor lubricity improving amount of a composition made by reacting component (A) with component (B) under salt-forming conditions; component (A) comprising a carboxylic acid represented by the formula R(COOH)n wherein R is a hydrocarbon group of 2 to 30 carbon atoms and n is a number in the range of 1 to 4, or an anhydride of said acid; and component (B) comprising a heterocylic aromatic amine.
Abstract:
The present invention is directed to an oil-soluble lubricating oil additive comprising at least one terminally unsaturated ethylene/alpha-olefin/diene interpolymer of 300 to 20,000 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 interpolymers 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:
A fuel additive composition comprising: a) a fuel-soluble aliphatic hydrocarbyl-substituted amine having at least one basic nitrogen atom wherein the hydrocarbyl group has a number average molecular weight of about 700 to 3,000; b) a polyolefin polymer of a C2 to C6 monoolefin, wherein the polymer has a number average molecular weight of about 350 to 3,000; and c) an aromatic di- or tri-carboxylic acid ester of formula (I), wherein R is an alkyl group of 4 to 20 carbon atoms, and x is 2 or 3.
Abstract:
This invention relates to metal salts of the general formula (I) A M , wherein M represents one or more metal ions, y is the total valence of all M and A represents one or more anion containing groups having a total of about y individual anionic moieties and each anion containing group is a group of formula (II), wherein T is selected from the group consisting of (V) or (VI) wherein each R is independently selected from O and OR wherein R is H or alkyl and each t is independently 0 or 1, wherein each Ar is independently an aromatic group of from 4 to about 30 carbon atoms having from 0 to 3 optional substituents selected from the group consisting of polyalkoxyalkyl, lower alkoxy, nitro, halo or combinations of two or more of said optional substituents, or an analog of such an aromatic group, wherein T is as hereinbefore defined, each R is independently alkyl, alkenyl or aryl having at least 8 carbon atoms, R is H or a hydrocarbyl group, R and R are each independently H or a hydrocarbyl group, each m is independently an integer ranging from 1 to about 10, x ranges from 0 to about 8, and each Z is independently OH, (OR )bOH or O wherein each R is independently a divalent hydrocarbyl group and b is a number ranging from 1 to about 30 and c ranges from 0 to about 3 with the proviso that when t in Formula (II) = 0, or when T is Formula (V), then c is not O provided that the sum of m, c and t does not exceed the unsatisfied valences of the corresponding Ar. Additive concentrates for preparing lubricants and fuels other than two-cycle engine lubricants and fuel compositions as well as lubricating compositions and fuel compositions other than those for two-cycle engines are also disclosed.
Abstract:
A fuel additive composition comprising: a) a poly(oxyalkylene) amine having at least one basic nitrogen and a sufficient number of oxyalkylene units to render the poly(oxyalkylene) amine soluble in hydrocarbons boiling in the gasoline or diesel range; and b) a polyalkyl hydroxyaromatic compound or salt thereof wherein the polyalkyl group has sufficient molecular weight and carbon chain length to render the polyalkyl hydroxyaromatic compound soluble in hydrocarbons boiling in the gasoline or diesel range.
Abstract:
A biodiesel fuel composition is provided to improve the combustion property of biodiesel using vegetable and animal oils as raw materials, by including perfluoro-alkanes. A biodiesel fuel composition is prepared by mixing 1-20 wt% of perfluoro-alkanes having five to eight carbon atoms and 0.5-25 wt% of MTBE(methyl-tertiary-butyl-ether), based on 100 wt% of normal biodiesel fuel. The biodiesel fuel composition further comprises normal gasoline additives consisting of an antioxidant, a metal activity depressant, an antifreezing agent, an anticorrosive, a preignition-inhibitor, a lubricant, a coloring agent, a detergent, or a mixture thereof.
