Electrochemical and theoretical quantum approaches on the inhibition of C1018 carbon steel corrosion in acidic medium using some newly phenolic Schiff bases compounds
Two novel Schiff bases, 5-bromo-2-[(_E_)-(pyridin-3-ylimino)methyl]phenol (HBSAP) and 5-bromo-2-[(E)-(quinolin-8-ylimino)methyl]phenol (HBSAQ) have been synthesized. They have been characterized by elemental analysis and spectroscopic techniques (UV–Vis, IR and NMR). Moreover, the molecular structure of HBSAP and HBSAQ compounds are determined by single crystal X-ray diffraction technique. The inhibition activity of HBSAP and HBSAQ for carbon steel in 3.5% NaCl + 0.1 M HCl ... إقراء المزيد
