Preparation of New Azo Dye Derived of Pharmaceutical Substances (Procaine and Vitamin B6) and Theoretically Studied as a Carbon Steel Corrosion Inhibitor

The amine drug procaine hydrochloride is employed in the preparation of the current azo dye, added to another drug, pyridoxine hydrochloride 2-(diethylamino) ethyl (Z)-4-(5hydroxyl-3,4-bis(hydroxymethyl)-6-methylpyridin-2-yl) benzoate.Chemical diagnosis of the prepared chemical compound was done using infrared technology, and mass spectrometry electron spectra were performed for the prepared compound in terms of its basic and acidic properties, which includes determining the protonation constant and the ionization constant at different pH values (2-12), as well as knowing the number of apparent isopiestic points.To the altar of mindful clarification to achieve the highest moisture of azo dye L (pH 12), several clarifying agents were prepared that gave a pH of 12.The theoretical study results also indicated that the new dye (L2) is not as effective at preventing corrosion in carbon steel as the original azo dye (L1) it comes from.Therefore, it is assumed from the above that the experimental results, if conducted, would need to demonstrate a corrosion inhibition efficiency of the inhibitor (L2) that exceeds the value of the inhibitor inhibition efficiency (L1), as predicted by the theoretical results in the computational chemistry program.
