Six derivatives of novel triazoles were produced from some substituted benzoic acid with thiocarbazide via method of grinding. The produced Chemicals were described via 1HNMR, IR, and 13CNMR spectra examinations. Produced derivatives of C2H3N3 were examined and assessed as reducing of corrosion in 0.5 M HCl for low-C steel utilizing procedure of losing weight. It was noticed that such chemicals had an encouraging act as reducer counter to mild steel corrosion of in solution being acidic. Reducing of maximum action was assessed at various concentrations and temperature of effector. Competence of corrosion reducer surpassed 96%. The exceptional action was due to inhibitor films adsorption development on surfacing steel. Reducing adsorption on surface of steel tracked Langmuir adsorption isotherm (LAI). The results were long-established BY theoretical calculations of quantum chemistry.
