US Patent:

55520693, Sep 3, 1996

Filed:

May 25, 1995

Appl. No.:

8/450826

Inventors:

Noyes L. Avery - Bryn Mawr PA
Joan C. Axelrod - Media PA
James T. Carey - Medford NJ
John Hiebert - Levittown PA
Andrew G. Horodysky - Cherry Hill NJ

Assignee:

Mobil Oil Corporation - Fairfax VA

International Classification:

C10M13536

US Classification:

508229

Abstract:

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.

US Classification:

44330

Abstract:

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.

US Patent:

Appl. No.:

8/444977

Inventors:

Noyes L. Avery - Bryn Mawr PA
James T. Carey - Medford NJ
John Hiebert - Levittown PA
Andrew G. Horodysky - Cherry Hill NJ

Assignee:

Mobil Oil Corporation - Fairfax VA

International Classification:

C10M13338

US Classification:

508229

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.
