摘要:
Alkylated thianthrenes are high temperature stable lubricant fluids having excellent thermal stability, antiwear and load-carrying properties and excellent additive solubility as well as multifunctional additives for fuels.
摘要:
Alkylated citric acid derivatives obtained as a reaction product of citric acid and an alkyl alcohol or an amine have been found to be effective antiwear and friction modifying additives for fuels and lubricants.
摘要:
Alkylated thiophene compounds are high temperature stable lubricant fluids having excellent thermal stability, antiwear and load-carrying properties and excellent additive solubility.
摘要:
Alkylated benzothiophenes or dibenzothiophenes are high-temperature stable lubricant fluids having extreme pressure and antiwear properties, additive solubility and inherent EP/antiwear properties. These novel fluids may also be used as additives in other lubricant fluids.
摘要:
Monoalkylated phenoxathins are high-temperature stable lubricant fluids having extreme pressure and antiwear properties, additive solubility and inherent EP/antiwear properties. These novel phenoxathin fluids may also be used as additives in other lubricant fluids and are prepared by alkyating a phenoxathin in the presence of an acidic zeolite catalyst.
摘要:
Lubricating oils containing olefin polymerizable acid esters and dimers and/or trimers thereof have been found to increase fuel economy in internal combustion engines. This is done by deposition of the additive on the lubricated surface.
摘要:
Polymerizable (that is, e.g., monomeric) polyfluorinated compounds, when added to a lubricant or to a liquid hydrocarbon fuel, as for example gasoline, will cause a reduction in fuel consumption. Reduced fuel consumption may also be realized for long periods from pistons and/or cylinder walls so coated with one or more of the polymerizable compounds.
摘要:
Lubricant compositions comprising an oil of lubricating viscosity and a minor proportion of water containing in an amount sufficient to counteract the accelerating effect of water on metal fatigue an amine salt of a half-ester of a substituted succinic acid. Greases containing the above-described amine salts are also provided.
