Abstract :
A new Heterocyclic organic inhibitor, having a triazole ring, linked with the quinoline ring namely 4-amino-1-((8-hydroxyquinolin-5-yl)methyl)-1,2,3- triazole-5-carbonitrile (AHTC) was prepared and identified by the usual methods as ¹H, ¹³C NMR and Elemental analysis. The influence of AHTC on the protection of XC38 steel against corrosion in 1.0 M HCl solution, have been studied using gravimetric and electrochemical measurement. The obtained results showed that its inhibition efficiency increases with concentration and reaches 90 % at 10⁻³ M. In addition, it is found that the AHTC takes its performance at the temperature range of 298–328 K and its adsorption was well described by the Langmuir isotherm at 298 K. On the other hand, the establishing of correlation between the molecular structures of quantum chemistry indices was carried out using the density func ional theory (DFT). Laboratory findings are in concordance with DFT results.
