Abstract:
The present invention relates to using a marker in a functional fluid, which survives the use of the functional fluid in an application, with a reagent solution to identify the functional fluid rapidly either before, during or after the functional fluid's use and which is a suitable method for identifying a functional fluid in the field, and which may employ the use of test wipe, or medium, that contains the reagent solution.
Abstract:
Compositions and methods for reducing stress corrosion cracking in steel vessels used for storing and/or transporting ethanol-containing fluids. Additives including oxygen scavengers and film-forming additives can be employed together in such ethanol-containing fluids (e.g., fuel grade ethanol) to mitigate stress corrosion cracking in steel vessels, such as pipelines, storage tanks, rail cars, and/or tanker trucks.
Abstract:
A fuel oil composition is disclosed. The fuel oil includes a major proportion of a fuel oil and minor amounts of: (a) at least one polar nitrogen compound effective as a max anti-settling additive; and (b) at least one reaction product between a hydrocarbayl-substituted succinic acid or anhydride and hydrazine.
Abstract:
There is described a fuel composition which is substantially free of alkoxylated compounds and is substantially free of long-chain alkyl alcohols having at least 6 C atoms, and contains at least 95% by volume of a hydrocarbon-based fuel and 0.1 to 5% by volume of an additive of the formula (I); R—CO—NR1R2 (I) in which R is a saturated or unsaturated, linear or branched alkyl radical having 6 to 21 C atoms; and R1 and R2, which may be the same or different, each represent a hydroxyalkyl radical having 1 to 4 atoms.
Abstract:
A stable liquid concentrate comprising a dye component which contains a substantial amount of a dye of the formula: wherein the dye component is dissolved in either an aliphatic hydrocarbon or an alicyclic hydrocarbon.
Abstract:
The present invention relates to gasoline or a gasoline and ethanol blend fuel compositions that have improved oxidation stability. More specifically, the gasoline or a gasoline and ethanol blend fuel compositions include at least one antioxidant that increases the oxidative stability of the fuel. The gasoline or a gasoline and ethanol blend fuel compositions may also include an antioxidant mixture, or an antioxidant mixture in combination with a polar and/or nonpolar solvent, that increases the oxidative stability of the fuel.
Abstract:
Fuels, especially hydrocarbon fuels, and lubricants, especially lubricating oils, contain a class of anti-corrosion, anti-fatigue, and anti-wear additives that are derived epoxidized esters of fatty acids. Epoxidized 2-ethylhexyl tallate is particularly effective.
Abstract:
Fuel compositions comprising a major amount of a normally liquid hydrocarbon based fuel and a minor amount of a compound having at least one strained ring group containing from 3 to 5 ring atoms.
Abstract:
The invention relates to combustion catalyst compositions which when blended into liquid hydrocarbon-base fuels reduce deposits in fuel combustion systems, inhibit corrosion in fuel systems and facilitate a more efficient oxidation of fuel. The combustion catalyst compositions comprise a surface-active/emulsifier agent, a lubricating oil and a liquid saturated hydrocarbon having the general formula C.sub.n H.sub.2n+2 wherein n is from 14 to 17.
