  • Patent number: 5482521
    Abstract: 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.
