摘要: In this work, the catalytic capacity of a Mg/Fe layered double hydroxide (LDH) and its mixed oxides to perform Huisgen cycloaddition was studied. The process performed in presence sodium ascorbate, which determinant for success 1,3-cycloaddition. obtained triazoles were evaluated as corrosion inhibitors using electrochemical impedance spectroscopy under static conditions, showing an inhibition efficiency higher than 95% at 50 ppm some According Langmuir isotherm, all compounds synthesized analysed exhibit chemisorption process. Finally, when submerging steel bar 1 M HCl studied SEM-EDS. This experiment showed that decreases considerably organic inhibitor.
