Read More The Iraqi oil field environment is filled with metal pipes and other components that are often exposed to chemicals that can cause corrosion, especially when the metal and chemicals are in a solution such as downhole fluids. Inhibitors are among the most important industrial additives that are commonly used in Iraqi petroleum industry to decrease the corrosion that cause damage to pipelines, water and waste water system. This fact evoked the urgent need to prepare corrosion inhibitor materials; one of the most important properties of these compounds is to act as surfactants working to remove or reduce the surface tension between the two immiscible phases with each other and make it easier to mix. Three types of corrosion inhibitors were prepared by using fatty acids and converted them into the fatty alkyl halides in presence of hydrochloric acid. Finally, the products reacted with various mole ratios of tertiary amine in various mole ratios, and then they were identified by classical methods melting point measurement, solubility test and [FTIR, 1H-NMR and 13C-NMR]. Morphology of the carbon steel was examined using scanning electron microscopy (SEM) in presence and absence of inhibitors. In the last step, the inhibitors of low carbon steel in acidic medium were assessed as a case study by using potentiostat device and weight loss to calculate the corrosion rate and inhibition efficiency. The result was as follows: P1 was 81.30%, P2 was 81.79% and P3 was 97.56%. In addition, inhibitors prepared in this study were evaluated in organic phase (Bazrcan iraqi oil fields) by weight loss method using different concentrations of corrosion inhibitors (50,75,100 ppm) and the inhibition efficiency as follows:P1: inhibition efficiency (91.8%) at a concentration of inhibitor (100 ppm);P2: inhibition efficiency (83.8%) at a concentration of inhibitor (100 ppm); andP3: inhibition efficiency (81.2%) at a concentration of inhibitor (100 ppm).
