N-(3-NITROBENZYLIDENE)-2-AMINOBENZOTHIAZOLE AS NEW LOCALLY AVAILABLE CORROSION INHIBITOR FOR IRAQI OIL INDUSTRY.

The inhibiting effect of a new locally available compound on the erosion of mild-steel surface used in Iraqi petroleum installations in 1 M HCl media has been investigated using different approaches. Weight loss technique was the first approach that was used for six various concentrations of N-(3- Nitrobenzylidene)-2-aminobenzothiazole of 0, 25, 100, 250, 500 and 1000 mg/L. The results showed that within the concentrations interval studied, the corrosion inhibition performance increased with increasing N-(3-Nitrobenzylidene)-2- aminobenzothiazole concentration. Scanning electron microscope (SEM) was the second approach employed to investigate the surface analysis and the morphology of the mild-steel surface without/with the use of N-(3-Nitrobenzylidene)-2- aminobenzothiazole as a corrosion inhibitor. The results indicated that N-(3- Nitrobenzylidene)-2-aminobenzothiazole showed excellent performance as mild steel corrosion inhibitor in corrosive media. [ABSTRACT FROM AUTHOR]
