Class Information
Number: 508/225
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.) > Compound of indeterminate structure, prepared by reacting a heterocyclic compound of known structure; a heterocyclic ring is one having as ring members only carbon and at least one hetero atom selected from nitrogen and chalcogen (oxygen, sulfur, selenium, or tellurium) > The heterocyclic compound reactant contains a three- or four-membered hetero ring (e.g., aziridine, epoxy compounds, oxetane, etc.) > An additional reactant contains nitrogen
Description: Compositions wherein nitrogen is present in an additional reactant.
