Abstract: Heterocyclic compounds having fused pyrimidine moieties with electron-donating groups. A method of preparing the heterocyclic compounds via a multicomponent condensation reaction is specified. These compounds are effective against corrosion of metallic substrates in acidic (i.e. CO2), and high salinity environments commonly found in oil and gas industry.

Abstract: Corrosion inhibiting compositions and methods of inhibiting corrosion on a metal surface commonly used in the petroleum industry is disclosed. The corrosion inhibitor includes at least one azole, at least one polypeptide derived from amino acid, at least one intensifier preferably from metal halides, and at least one surfactant. The methods include combining effective amounts of the corrosion inhibitor composition and contacting a metal surface in aqueous environment commonly found in oil and gas industry. The composition is very effective against corrosion of metals in contact with aqueous media when used in a dosage as low as 50 ppm.

Abstract: Corrosion inhibiting formulations including a substituted benzimidazole, a mercaptocarboxylic acid, a 2-thioxodihydropyrimidine-dione, a sulfhydryl alcohol, a surfactant, and a solvent. Methods for preventing, inhibiting, or reducing metal (e.g. carbon steel) corrosion utilizing these formulations are described. The formulations are effective against corrosion of metallic substrates in sweet (i.e. CO2), sour (i.e. H2S), and/or high salinity environments commonly found in petroleum industry.

Abstract: A method for enhancing adhesion of a curable composition to a cement-based object includes applying a graphene oxide (GO) containing dispersion on a surface of the cement-based object thereby forming a GO-treated surface on the cement-based object. The method includes disposing the curable composition on the GO-treated surface of the cement-based object. The method includes curing the curable composition by heating thereby forming a GO interfacial layer and an epoxy resin layer. The GO interfacial layer is between the surface of the cement-based object and the epoxy resin layer. The curable composition includes an epoxy monomer and an amine curing agent. The GO interfacial layer has a thickness of from 0.1 to 10 nanometers (nm).
