Abstract—The experiment for API grade steel has been carried out by using weight loss measurement technique. All the experiments were carried out in an autoclave at varying temperature and a fixed partial pressure of carbon dioxide. The different concentration of imidazoline as organic inhibitor has been added in the solution to know the inhibition effect on the metal surface. The results indicated that addition of 40 ppm of inhibitor showed the higher efficiency due to the formation of more adhered and protective film over the metal surface. The exposed samples were characterized by using various techniques such as x-ray photoelectron spectroscopy and scanning electron microscopy
