Abstract:
Sulfurized olefins having no detectable reactive olefinic bonds, particularly sulfurized isobutylene, are reacted with dihydrocarbyl phosphates or phosphites. The resulting product is useful as an extreme pressure and wear additive for lube oil compositions.
Abstract:
Disclosed is an additive for liquid hydrocarbon fuel composition, particularly diesel fuels. The additive composition is the reaction product of polyalkenyl-substituted succinimides, aldehydes, and triazoles. It also finds use in lubricant compositions.
Abstract:
Additives which improve the low-temperature properties of distillate fuels are the oligomeric/polymeric reaction products of aromatic anhydrides and epoxides (or their corresponding acid/diol equivalents), with optional termonomers.
Abstract:
Additives which improve the low-temperature properties of distillate fuels are the polymeric and/or oligomeric monomers selected from ester/urethane reaction products of a combination of anhydrides and epoxides (or their corresponding acid/diol equivalents), and a urethane precursor and optionally with various suitable reactive materials to provide optional termonomers.
Abstract:
Dialky and trialky phosphites are reacted with sulfur. The resulting product is the desired lubricant additive which is mixed with suitable lubricating oils.
Abstract:
A fuel composition contains an antiwear additive comprising the reaction product of a fatty acid salt comprising oleic acid, stearic acid, tall oil acid and dimer acid having 10 to 40 carbon atoms and an aromatic triazole such as tolyltriazole and method of making the same.
Abstract:
Borated hydroxyalkyl esters of alkyl- or alkenylsuccinimide-derived dithiocarbamic acids, have been found to be effective multifunctional additives in lubricant and fuel applications.
Abstract:
The low-temperature properties of distillate fuels are improved when reaction products of pyromellitic dianhydride and amonoalcohols and/or amines with long chain hydrocarbyl groups are incorporated therein.
Abstract:
An ashless detergent additive having antioxidant and metal surface protection properties for lubricants or fuels is made from a Mannich condensation reaction between a hydrocarbylbissuccinimide, such as a dimer of a polyisobutenylsuccinimide (derived from tetraethylenepentamine), an aldehyde, such as formaldehyde, and a heteroatom substituted benzoic acid such as salicyclic acid, thiosalicyclic acid or aminosalicylic acid.
Abstract:
Disclosed is an additive for lubricant or fuel composition comprising the boronated reaction product of polyalkenyl-substituted succinimides, aldehydes and triazoles.
