The corrosion inhibition performance of 2-hydrazino-4,6-dimethoxy-1,3,5-tirazine (DMeHT), 2,4-dihydrazino-6-methoxy-1,3,5-triaizine (DHMeT), and 2,4,6-tridydrazino-1,3,5-triaizne (TH₃) on steel corrosion in acidic media was examined using electrochemical techniques. The results showed 2,4-Ddihydrazino-6-methoxy-1,3,5-triaizine (DHMeT) gave the best corrosion protection performance among the oth...

a quantum chemical study of the corrosion inhibition properties of some organic inhibitormolecules, pyridine, 2-picoline, 3-picoline, 4-picoline, 2, 4-lutidine at the aluminum surface inhydrochloric acid (hcl) was carried out. the models of the inhibitors adsorption on the al-surfacewere optimized with the hf and b3lyp level using the 6-31g and lanl2dz basis sets fromthe program package gaussia...

Abstract Objectives A regioselective approach has been developed for the synthesis of benzopyranophenazine derivatives using In (OTf)3 as a catalyst in one‐pot synthesis. Further, these synthesized compounds were successfully used organic corrosion inhibitors on mild steel 1M H2SO4 solution. Methods The confirmed NMR, and HRMS their regioselectivity was by DFT studies B3LYP/6‐31G (d, p) basis s...

The corrosion inhibition properties of some organic dyes, namely Sunset Yellow (SS), Amaranth (AM), Allura Red (AR), Tartrazine (TZ) and Fast Green (FG), for mild steel corrosion in 0.5 M HCl solution, were investigated using gravimetric, potentiodynamic polarization techniques and quantum chemical calculations. The results showed that the studied dyes are good corrosion inhibitors with enhance...

Evaluation of corrosion inhibitors for steel in acidic media is important for some industrial facilities as well as is very interesting from theoretical aspects. Most of the effective inhibitors are organic compounds containing nitrogen, phosphorus and sulphur in their structures [1, 2]. Heteroatoms such as nitrogen, oxygen and sulphur are capable of forming coordinate covalent bond with metal ...
