The College of Education for Pure Sciences discussed a doctoral thesis on the preparation and identification of some azo and azomethine compounds and their use as new inhibitors for the corrosion of carbon steel in oil wells.
The thesis presented by the researcher (Abeer Mohammed Jabbar) included a study of the preparation of two series of organic compounds: The first series is the preparation of azo compounds (A3-A1) derived from phenol (4-chloro-3,5- dimethyl phenol) with different amines by the method of nitrogenation and coupling.
As for the other series of azomethine compounds (S3-S1), it is derived from aldehyde (1,4-benzodioxane-6-carboxaldehyde) with different amines by the method of reflux distillation.
The prepared compounds were identified through spectroscopic techniques, namely infrared spectroscopy FT-IR, proton and carbon nuclear magnetic resonance spectroscopy 1H,13C-NMR, and mass spectroscopy EI-Mass.
All the prepared compounds were used at different concentrations (50, 10, 5, 1)*10-3 M as organic corrosion inhibitors compared with the commercial inhibitor for carbon steel N80 alloy in acidic environment with a concentration of (1M) hydrochloric acid and for different range of temperatures using the dynamic polarization method (extrapolation of Tafel plot).

Computational chemistry was also used in the study.

The prepared compounds were shown to be inhibitors against corrosion.
