A rapid and new synthetic route for N,N'-di-o-tolyl guanidine (DTG) synthesis from cheap materials is reported. The performance of DTG as an excellent inhibitor delaying copper (Cu) corrosion with efficiency higher than 98% at 20 × 10-6 M in acidic solution was investigated via electrochemical measurements. These measurements included PDP, EFM, EIS spectroscopy. experimental data indicated that has efficient inhibiting effect on the Cu media.The adsorbed to surface chemical adsorption followed Langmuir route. PDP revealed acted a mixed inhibitor. Furthermore, showed through metal/electrolyte interface. This resulted forming protective layer surface, thereby impeding dissolution solution. corrosive containing after immersion specimen 48 h, which promoted formation complex between cation DTG, ultraviolet/visible In addition, confirmed scanning electron microscopy atomic force analysis morphology. Moreover, active centers interaction were silico evaluation DTG.
