Facile synthesis of palmitic acid polyacrylamide and its application for steel protection from corrosion using electrochemical determination

Steel-corroding protection has been one of the most important research fields because of the great significance of steel in national defense, industry and our daily life. In the presented work, a novel corrosion inhibitor and its corrosion-inhibiting performance which was determined by an electrochemical approach supported with weight-loss method were reported. The presented inhibitor, i.e., palmitic acid polyacrylamide, was synthesized via a requrqitant condensation route in the presence of palmitic acid, ethylenediamine and dimethyl benzene. The optimal preparing conditions were obtained by orthogonal experiments, and the corrosion-inhibiting property of palmitic acid polyacrylamide at different concentration was also investigated. The results show that the corrosion-inhibiting efficiency was up to 78.1%, indicating its potential application for protecting steel from corrosion in national defense, industry and our daily life.
