Class Information
Number: 508/240
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 carboxylic acid anhydride ring > An additional reactant is a hydroxylamine or an alcoholic or phenolic hydroxy compound > Nitrogen attached directly or indirectly to the hydroxy group by nonionic bonding
Description: Compositions wherein the hydroxy group of the additional reactant is attached directly or indirectly to nitrogen by nonionic bonding.
