Evaluation of Percentage Corrosion Inhibition Efficiency of Mild Steel with Derivatives of Oxazolone

Gitalee Sharma, Parijat Burahgohain


 Carbon Steel is one of the most widely used material in the transportation pipelines of Oil and Gas industry. However, they are prone to corrosion in acidic environment. As preventive measure various mitigation techniques are employed to bring a stag to its corrosion, one of which is the use of inhibitors. In the paper, the study of the inhibitive properties of two oxazolone derivatives have been reported. The compounds were synthesized at ease and in high yield. The corrosion studies were performed on carbon steel in three different concentrations of HCl (1N, 1.5N and 2.0N) solutions using weight loss coupon (gravimetric) method. 1N HCl solution was found to have the most effective inhibition property for the oxazolone derivatives. % Inhibition efficiency was found to be maximum with 100 ppm of inhibitor concentration. The results revealed oxazolone derivatives as promising effective corrosion inhibitors.
