structure of the three prepared compounds. These heterocyclic compounds are chemically stable and possess multi actions for base oil improvement. They are tested as antioxidants for local base oil through the change in total acid number (TAN). They gave good results as antioxidants base oil. Also these three synthesized compounds are tested as corrosion inhibitors for carbon steel in acid medium. The efficiency
