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.

Multifunctional ashless detergent additives for fuels and lubricants

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.

A fuel composition contains an antiwear additive comprising the reaction product of heterocyclic compound having antiwear activity such as a triazole e.g. benzotriazole, tolyltriazole, and a copolymer with succinic anhydride moiety, such as an olefin/maleic anhydride copolymer.

Olefin/maleic anhydride copolymer heterocyclic-azoles as antiwear

Products of reaction between 1-alkyl-N,N-dialkyl ethanolamines and copolymers of maleic anhydride are new additives which are effective in lowering the cloud point of distillate fuels.
