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:
A method including using an alkyl halide, such as but not limited to, tetrabromoethane, as a fuel additive to a fuel to increase completeness of combustion of the fuel.
Abstract:
Compositions comprising hydroxyl group containing acylated nitrogen compounds, a process for reacting certain carboxylic reactants with olefinic compounds then reacting the product prepared thereby with ammonia, a hydrazine or an amine, products prepared thereby and lubricating oil and fuel compositions.
Abstract:
The invention concerns an organic sol characterised in that it comprises cerium oxide particles, an organic liquid phase and at least an amphiphilic compound selected among carboxylic acid polyoxyethylene alkyl ethers, polyethylene phosphate alkyl ethers, dialkyl sulphosuccinates and quaternary ammonium compounds. In a first embodiment, the method for preparing the sol is characterised in that it consists in mixing said amphiphilic compound and the organic liquid phase, then in dispersing the cerium oxide particles in the resulting mixture. In a second embodiment, the method consists in forming a mixture of cerium oxide and at least one said amphiphilic compound, then in dispersing said mixture in said organic liquid phase. The invention also concerns a solid compound comprising a mixture of cerium oxide and at least an amphiphilic compound selected among those mentioned above.
Abstract:

Abstract:
A fuel additive composition comprising: (a) a fuel-soluble aliphatic amine selected from the group consisting of (1) a straight or branched chain hydrocarbyl-substituted amine, (2) a hydroxyalkyl substituted amine, and (3) a straight or branched chain hydrocarbyl-substituted succinimide; 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.
