Class Information
Number: 508/242
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) > An additional reactant is a phenol, a thiophenol, a carboxylic acid, or salt thereof
Description: Compositions wherein a phenol, a phenol salt, a thiophenol, a thiophenol salt, a carboxylic acid, or a carboxylic acid salt is an additional reactant.
