Synthesis, characterization, and electrochemical studies of novel biphenyl based compounds / R. Baskar in Industrial & engineering chemistry research, Vol. 51 N° 10 (Mars 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 10 (Mars 2012) . - pp. 3966–3974 Titre : Synthesis, characterization, and electrochemical studies of novel biphenyl based compounds Type de document : texte imprimé Auteurs : R. Baskar, Auteur ; M. Gopiraman, Auteur ; D. Kesavan, Auteur Année de publication : 2012 Article en page(s) : pp. 3966–3974 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Electrochemical  Biphenyl Résumé : (2E)-1-(Biphenyl-4-yl)-3-(4-nitrophenyl)prop-2-en-1-one (BNO), (2E)-3-(4-aminophenyl)-1-(biphenyl-4-yl) prop-2-en-1-one (BNH), and (2E)-1-(biphenyl-4-yl)-3-(4-hydroxyphenyl)prop-2-en-1-one (BOH) were synthesized and characterized by FT-NMR, FT-IR, and elemental analysis. The synthesized compounds were investigated for corrosion inhibition of mild steel in hydrochloric acid medium by means of weight loss measurements, polarization studies, electrochemical impedance spectra, and the adsorption isotherm. Among the biphenyl chalcone derivatives, BOH showed higher efficiency against corrosion of mild steel. All the inhibitors were predominantly found to be cathodic in nature. The thermodynamic parameter values of the free energy of adsorption (ΔGads) reveals that inhibitor was adsorbed on the mild steel surface and the adsorption mechanism of inhibition was supported by FT-IR, surface analysis (SEM-EDS), and adsorption isotherms.
