Oxygenated alkyl amines synthesized using carbonyl coupling reactions have combustion chamber deposit reducing properties and oxidative stability characteristics beneficial for dispersant/detergent applications in fuels and lubricants.

Fuel composition with reaction product of oxygenated amine, dicarbonyl

Polyalkylene amine coupled carboxylates are effective multifunctional additives, providing cleanliness to fuels and lubricants as well as friction-reducing and corrosion-inhibiting properties.

Additives for fuels and lubricants

Polyalkylene amine coupled heterocyclic compounds are effective multifunctional additives, providing cleanliness to fuels and lubricants as well as anti-wear, friction-modifying, thermal and oxidative stabilizing properties. The beneficial effects of the product of the instant invention apparently result from an internal synergism between the polyalkylene amine groups and the heterocyclic groups.

The invention relates to lubricant and fuel additives having antiwear and friction reducing properties. The invention also relates to compositions of oils with viscosities appropriate for lubricants, greases produced therefrom, and fuels and methods for making these compositions. Described in this invention are products of nitrogen heterocycles, such as benzotriazole and tolyltriazole, with amines, such as alkyl amines, aliphatic diamines, alicyclic amines, heterocyclic amines, propylene amines, and aliphatic etheramines, that are linked using carbonyl compounds (e.g., aldehyde, ketone or glyoxal). Additionally, products generated by the reaction of carboxylic acids or carboxylic acid generating compounds (e.g., salts or esters) with carbonyl (e.g., aldehyde, ketone or glyoxal) coupled nitrogen heterocycles and amines, including those described above, are also included in this invention. These products can be used in fuels and lubricants to produce improved antiwear and friction reducing properties.

Friction modifiers and antiwear additives for fuels and lubricants

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.
