Dr. Uday Hadi Rauf, professor Dr. Soad Mohammed Hussein and professor Dr. khuloud Abid Saleh, instructors in the department of chemistry at the college of science, university of Baghdad, got a new patent issued by the central organization for standardization and quality control, industrial property department. This new patent is entitled “preparation, diagnosis and evaluation of some new derivatives of 2-aroil slvanil H1-bnzaimidazol as inhibitors of corrosion of iron steel in sulphuric acid” that is prepared jointly by the senior chemist Walid Ismail Amara who is a researcher at the center for research and development at the oil ministry. The importance of the patent attained by the chemical researchers at the university of Baghdad comes after studying the rate of corrosion of steel iron, the value of the rate of this erosion that they considered as a complex equation for many of these factors that are often inconsistent and in flux. The researchers showed that the problem of corrosion, especially in steel iron is one of the more complex issues in comparison with other types because the corrosion rate is not governed by certain mathematical rules on which we can learn the age of the metal part exposed to corrosion unlike the chemical factors relevant to inhibitors to estimate corrosion rates and the impact of various factors in this rate alone or in combination. The researchers consider corrosion a deterioration of materials by a chemical reaction with metals since iron is the most used metal.
