摘要：In the present investigation, a new organic inhibitor, namely N - ((8 - hydroxyquinolin - 5 - yl) methyl ) - N - phenylacetamide (HQMP) was synthesized and characterized using 1 H, 13 C NMR and IR spectroscopies . In the second time, the inhibition effect of HQMP on the steel XC38 corrosion in 1 M HCl , have been investigated using electrochemical measurements. The o btain ed results show ed that the its inhibition efficiency increased with concentration and reached 93 % at 10 - 3 M. in addition, t he HQMP takes its performance at the temperature range of 298 – 328 K . T he adsorption of the inhibitor on the mild steel was well described by the Langmuir isotherm. On the other hand, the establishing of correlation between the molecular structure of quantum chemistry indices was carried out using the density functional theory (DFT).
