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: Additives which improve the low-temperature properties of distillate fuels are the oligomeric/polymeric reaction products of one or more bicyclic or alkyl anhydrides or their diacid equivalents and one or more long-chain epoxides or their corresponding acid/diol equivalents, with optional termonomers.

Abstract: A fuel additive is the reaction product of an intermediate reaction product of a hydrocarbon-substituted succinic anhydride and an aminosalicylic acid, preferably a 4-aminosalicylic acid. The intermediate is reacted with an aldehyde, preferably formaldehyde and an alkylenepolyamine preferably tetraethylenepentamine. The reaction product is post reacted with a hydrocarbon-substituted succinic anhydride which can be the same or different as the hydrocarbon-substituted succinic anhydride of the intermediate. The additive has dispersant and detergent properties and is effective in liquid hydrocarbon or liquid oxygenated fuels or mixtures of the said fuels.

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 salicylic acid, thiosalicylic acid or aminosalicylic acid.

Abstract: Reaction products in which polyethers are connected to hydroxyalkylated polyamines using diisocyanates have been found to be effective ashless dispersants and detergents for various lubricants and fuels.

Abstract: A multifunctional antioxidant, antiwear and dispersancy additive for fuels and lubricants is a reaction product of a thiol-substituted diazole, such as aminomercaptothiadiazole (AMTD) or dimercaptothiadiazole (DMTD), an aldehyde and a hydrocarbon-substituted succinimide dimer. The succinimide dimer is derived from polyisobutenyl succinimide and tetraethylenepentamine which are reacted in a mole ratio of 2:1.
