Class Information
Number: 508/287
Name: Solid anti-friction devices, materials therefor, lubricant or separant compositions for moving solid surfaces, and miscellaneous mineral oil compositions > Lubricants or separants for moving solid surfaces and miscellaneous mineral oil compositions (e.g., water containing, etc.) > Heterocyclic ring compound; a heterocyclic ring is one having as ring members only carbon and at least one hetero atom selected from nitrogen and chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) > The hetero ring contains five members including nitrogen and carbon (e.g., polyvinylpyrrolidone, etc.) > Plural oxygens double bonded directly to ring carbons of the hetero ring which are adjacent to the ring nitrogen
Description: Compositions wherein two carbons of the hetero ring, each adjacent to the ring nitrogen atom, are double bonded directly to oxygen.
