Description
Summary:In this work, 2-acrylamido-2-methylpropane sulfonic acid-CO-lauryl acrylate copolymer is used in the synthesis of three new anionic polymeric surfactants for use in corrosion protection of petroleum pipelines composed of carbon steel alloy. The corrosion inhibition performance of the prepared inhibitors was measured using weight loss and electrochemical methods in 1M HCL. The morphology of untreated and treated carbon steel surfaces was studied by scanning electron microscopy (SEM). Also, the thermodynamic properties as well as surface tension were investigated for the prepared inhibitors. Adsorption phenomena for the prepared surfactants on the carbon steel alloy were found to obey Langmuir's law. The quantum chemical parameters as highest occupied molecular orbital (EHOMO), lowest unoccupied molecular orbital (ELUMO) and energy gap (ΔE) were computed for the prepared inhibitors and it was found that LP3 had higher efficiency than others.
